Move the network buffer header file from zephyr/net/buf.h to

subsystem.

Add (deprecated) zephyr/net/buf.h header to maintain compatibility with old

4c9ee14572 Bluetooth: Mesh: Allow to suspend mesh from bt_mesh_send_cb callbacks
This commit allows to suspend the mesh stack from `bt_mesh_send_cb`
callbacks by removing the deadlock caused by `k_work_flush` in the
extended advertiser.

In case of the extended advertiser there are 2 cases:
- when the `bt_mesh_adv_disable` is called from any of `bt_mesh_send_cb`
  callbacks which are called from the advertiser work item, or
- when it is called from any other context.

When it is called from `bt_mesh_send_cb` callbacks, since these
callbacks are called from the delayable work which is running on the
system workqueue, the advertiser can check the current context and its
work state. If the function is called from the advertiser work, it can
disable the advertising set straight away because all ble host APIs have
already been called in `adv_start` function. Before sending anything
else, the advertiser checks the `instance` value in `adv_start`
function, which is also reset to NULL in `bt_mesh_adv_disable` call, and
aborts all next advertisements. The `ADV_FLAG_SUSPENDING` tells the
advertiser work to abort processing while `bt_mesh_adv_disable` function
didn't finish stopping advertising set. This can happen if the work has
been already scheduled and the schedler ran it while sleeping inside
the `bt_le_ext_adv_stop` or `bt_le_ext_adv_disable` functions.

When `bt_mesh_adv_disable` is called from any other context or from the
system workqueue but not from the advertiser work, then `k_work_flush`
can be called safely as it won't cause any deadlocks.

The `adv_sent` function is inside the `bt_mesh_adv_disable` function to
schedule the advertiser work (`send_pending_adv`) and abort all pending
advertisements that have been already added to the pool.

In case of the legacy advertiser, if the `bt_mesh_adv_disable` is called
form the advertiser thread (this happens when it is called from
`bt_mesh_send_cb.start` or `bt_mesh_send_cb.end` callbacks), then
`k_thread_join` returns `-EDEADLK`. But the `enabled` flag is set to
false and the thread will abort the current advertisement and the
pending advertisements.

c601c15863 Bluetooth: Mesh: Remove extra rescheduling and ADV_FLAG_SCHEDULED in adv
This commit removes extra rescheduling in the extended advertiser after
the last advertising has been finished. This commit also removes the
`ADV_FLAG_SCHEDULED` flag as not needed anymore.

This extra rescheduling and the flag were needed to delay the next
advertisement by 20ms. Now, when the delay is removed the advertiser can
pick the next advertisement from the pool and push to the host right
away.

9af051e349 Bluetooth: Mesh: Call bt_mesh_send_cb.end cb by the end of adv
Before this change, the bt_mesh_send_cb.end callback was called when all
references to the adv were removed. If an implementation kept more
references to the adv buffer after calling `bt_mesh_adv_send`, the end
callback would not be called when the advertiser finished advertising
this adv.

With this change, the end callback is always called by the advertiser
when the advertisement is finished regardless of the number of
references. This allows an implementation to keep the adv buffer for the
future use. As an example, pb_adv.c keeps advs for retransmission.

The recommendation to have 20ms is fair for two

sends two messages it can be interpreted as two
bearers working in parallel. No need to keep
an artificial 20ms delay for that. Delay was
removed and all related bsim tests were fixed.

Adds a disable function for the extended advertising which stops and
deletes the advertising instances, allowing them to be properly
reinitialized when calling `bt_mesh_adv_enable()` after bluetooth has
been disabled and re-enabled.

For the legacy advertising, the function terminates the advertising
thread. If legacy advertising is used, `bt_mesh_adv_init()` must be
called before `bt_mesh_adv_enable()` to properly resume advertising
after suspension.

Reschedule dedicated relay adv sets immediatey after finishing
advertising of the previous relay message. This allows a node to
relay messages as fast as possible when Relay Retransmit Count state
is zero using less relay adv sets.

When Relay Retransmit Count state is non-zero, the delay doesn't do
anything as the time between pushing a relay message to the host and
triggering adv_sent callback will be greater than this delay. In this
case the relay adv set will send a next message immediately.

- On-Demand Private Proxy functionality (Server and Client) controlling
  behaviour of node after receiving Solicitation PDU
- Solicitation PDU RPL Configuration (Server and Client), which manages
  Replay Protection List for Solicitation PDUs.

Proxy Solicitation allows to enable advertising of Proxy service on node
by sending Solicitation PDUs. These PDUs are not part of Mesh messages;
instead, these are non-connectable, undirected advertising PDUs with
their own format, containing Proxy Solicitation UUID.

- `/BT_INFO/LOG_INF/`
- `/BT_HEXDUMP_DBG/LOG_HEXDUMP_DBG/`
- `/BT_DBG_OBJ_ID/LOG_DBG_OBJ_ID/`

Also, some files were relying on the `common/log.h` include to include
`zephyr/bluetooth/hci.h`, in those cases the include of `hci.h` has
been added.

For files that were including `common/log.h` but not using any logs,

79e6b0e0f6 includes: prefer <zephyr/kernel.h> over <zephyr/zephyr.h>
As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.

The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.

NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

Another file in the separation is called proxy_msg.c,
which is used to process Proxy pdu messages.

Also according to Trond's suggestion:

Rename `CONFIG_BT_MESH_PROXY` to `CONFIG_BT_MESH_GATT`.
Create an additional promptless entry
`CONFIG_BT_MESH_GATT_SERVER` that selects
`CONFIG_BT_MESH_GATT` and is selected by
`CONFIG_BT_MESH_GATT_PROXY` or `CONFIG_BT_MESH_PB_GATT`.
