Commit adds analyzing of returned status of element rx.
If at least one element receives multicast message then
access layer will return suceess status.
If option CONFIG_BT_MESH_ACCESS_LAYER_MSG is enabled then
access layer will return success always.
Function bt_mesh_access_recv has been introduced to cover
case when real model statuses should be returned over
oppcode aggregator model despite access returns success.

Adds support for composition data page 2 & 130.
In this implementation the responsibillity for filling the page 2
buffer is left to the application through the new comp page 2 cb API.
Only the application can know/decide if the device is NLC compliant,
and must thus be given the responsibillity for cheking the NLC profile
requirements, defined in the NLC specs, and filling the response buffer
for comp data page 2.

This commit adds the following features related to virtual addresses
support:
- Allows to store Label UUIDs which virtual addresses collide;
- Allows to decrypt messages encrypted with a virtual address with
collision;
- Allows to publish a message to a specific Label UUID to avoid virtual
addresses collision by adding a pointer to Label UUID to
struct bt_mesh_msg_ctx and struct bt_mesh_model_pub;
- Allows to differentiate Label UUIDs in the model's Subscription List
by storing all subscribed UUIDs in struct bt_mesh_model.uuids field.

Mesh models may have a data that needs to be stored persistently.
Currently, the models should call bt_mesh_model_data_store and the store
will happen in the calling context. Most likely that it will be called
in BT RX thread as this is the context from which model's opcodes
handlers are called. Thus, the thread will be blocked until the store is
finished.
Another issues is that some models may have states that changes
frequently. Triggering the store on every state change may wear out
flash. Therefore, the models need to implement some postpone mechanism
to reduce the flash wear out.
The mesh stack has already implemented the mechanism of deferred store
with its own settings. The models could use it instead of implementing
their own mechanism.
In combination with the mesh settings workqueue, the models can store
their data without blocking the stack work.

This allows to move flash operations from the context that triggered
bt_mesh_provision or bt_mesh_reprovision to the mesh settings work item
that runs on the system workqueue. This is required to for a case where
the mesh settings work item is running on a separate thread instead of
the system workqueue to unblock the system workqueue eventually.

Composition data page 128 represents the new composition data after a
composition refresh procedure. The implementation stores the old
composition data (before applying a DFU or similar), and uses that as
page 0 if present. As the device has already rebooted by the time page
128 becomes active, its active composition data is page 128, while the
backed up data is the "old" data, which should be shown as page 0.

The existing extension tree does not support all the features that are
defined by the specification (e.g. multiple parents).
This patch approaches this problem by defining a circular single-linked
list of extension models. So for a given model, all models that are on
the same list as that model are in some extension relationship with that
model. All models on a list represent a single connected component of an
extension graph but without defining specific relationships between each
pair of models. This list is used to manage a shared subscription list
as per the Mesh Profile Specification:
```4.2.4 Subscription List
Within an element, each model has a separate instance of a Subscription
List, unless the model extends another model on that element. Instances
of models that extend other models (i.e., all models within an extension
relation tree) shall share a single instance of a Subscription List per
element.
```

Added bt_mesh_msg_send() which can be used by the application to
directly send model layer messages without local instantiation of
related models. Also added bt_mesh_msg_cb_set() which allows the
application to recieve mesh model layer messages without local
instantiation of related models.
Added bt_mesh_has_addr() which returns a bool. For unicast addresses,
this returns whether or not bt_mesh_elem_find() was successfull. If the
above mentioned bt_mesh_msg_cb_set() has been used by the application to
set a message callback, this returns true so that the stack attempts to
push every model message up to the application via the callback. If no
callback has been set, group addresses are searched to see if the stack
should pass the message up the stack to an instantiated model.
These changes allow applications that do not or can not instantiate
models to interface with models in a mesh network. This is applicable to
applications which act as a Bluetooth mesh gateway, sniffer, debugger,
network monitoring, non-mesh relay/extender, etc.
In app_keys.c friend.c net.c bt_mesh_elem_find() is used only to
determine the existance of an address. The full return value of
bt_mesh_elem_find() is unecessary and so was replaced by the above
mentioned bt_mesh_has_addr() function in these instances.
Simplified bt_mesh_elem_find() by removing the search through group
address. Since the above mentioned bt_mesh_has_addr() function handles
instances where group addresses must be searched, it was no longer
necessary to preform this search in this function.

The mesh settings.c module is a giant piece of code responsible for
storing the mesh stack configuration. Such approach makes it difficult
to control the data to be stored, breaks the stack modules'
encapsulation by forcing them to reveal the internal kitchen, which
leads to unpleasant issues such as #19799.
This commit moves the responsibility of storing the configuration
to corresponding modules while keeping control of the moment of storing
the configuration and of starting the stack after the settingss loading
is completed.
This doesn't introduce any abstraction between the mesh settings.c and
other modules as it will add more complexity and overhead than necessary
for the actual task.

Moves mesh feature configuration to a separate module, deprecating the
bt_mesh_cfg_srv structure. The initial values for the features should
now be enabled through KConfig, where new config entries have been added
for each feature.
This removes the upward dependency on the config server from the core
stack, and makes the config server a pure frontend for the configuration
states, as all spec mandated behavior around the feature states is now
encapsulated.

Adds the model extension concept to the access layer, as described in
the Mesh Profile Specification, Section 2.3.6. Extensions are
implemented as a tree, using two pointers in each model:
The extends pointer points to the first extended model, and the next
pointer points to the next sibling or (if the NEXT_IS_PARENT flag is
set) the parent model in the tree, forming a cyclical "Left-child
right-sibling" (LCRS) tree. The tree root can be obtained by calling
bt_mesh_model_root_get(), and the extended models can be walked by
calling bt_mesh_model_tree_walk().
According to the Mesh Profile Specification Section 4.2.3, all models in
the same extension tree share one subscription list per element. This is
implemented by walking the model's extension tree, and pooling the
subscription lists of all models in the same element into one. If the
config server adds a subscription to a model, it may be stored in any of
the model tree's models' subscription lists. No two models in the same
extension tree and element will have duplicate groups listed. This
allows us to increase extended models' capacity for subscriptions
significantly.
