2ab5882e0b Bluetooth: CAP: Add cap_unicast_group API
Adds a new abstract struct for unicast group that is
specific for CAP. The difference between this and the BAP
unicast group, is that the parameters are CAP streams and
thus ensuring that the streams in the group adhere to the
additional requirements that CAP has on top of BAP.

This also adds foreach functions for both CAP and BAP
to allow users to iterate on the streams in the
abstract groups.

Various samples, modules and tests have been updated
to use the CAP struct and API.

52f089af23 Bluetooth: CSIP: Set member: Fix issue with re-registration
The bt_csip_set_member_register kept a counter that was not
decreased when bt_csip_set_member_unregister was called.
This meant that we could register and unregister CSIS,
but we could not re-register once it had been unregistered.

This commit fixes this by removing the counter and instead
rely on the service instance state, which also requires restoring
the original service definition, as well as adding a test that would
have failed with the previous version.

The context type PROHIBITED has been removed from
the Bluetooth assigned numbers document. It is, however,
still used in some profiles to indicate either "No context
type supported" or "None available", and thus a rename
to "NONE" makes sense.

It is still treating similar to prohibited in some cases,
as it is not a valid context type in all cases.

11c3ee12a8 Bluetooth: BAP: Sink: Move mod_src_param to RAM
The mod_src_param was several places stored on the stack.
However this is a complex paramater struct that has
2 Kconfig options that can significantly increase the size,
and the maximum size of the parameter is nearly 8 KiB, and
was always place the in the BT RX thread's stack.

For this reason, the param is now stored in a single
static variable in RAM instead, so that the BT RX thread's stack
does not need to be increased based on the Kconfig options,
as that is quite difficult for users to be aware of.

The add_src_param has been left as is, as that stored in
the calling thread, and it is easier for an application
to determine if the calling thread needs additional stack
space.

065dca7e92 Bluetooth: ISO: Make setting ISO data explicit
The stack will no longer implicitly set the data path
for ISO channel, and the responsibility for doing that is
now for the upper layers/applications.

This provides additional flexibility for the higher layers
as they can better control the values and timing of the data
path, as well as support removing and even reconfiguring the
data path at will.
This also removes some complexity from the stack.

This commit also fixed a inconsistency in the disconnected
handler. CIS for centrals as well as BIS were still valid
bt_iso_chan channels in the disconnected callback,
but CIS for peripherals were completely cleaned up at this
point. This issue is fixed by moving the disconnected callback
handling to before the code to cleanup the channel for
peripherals.

Since there is a difference in how you remove data paths
depending on the GAP role (central/peripheral), the
iso_info struct type has been expanded to be more
concise of which type of CIS it is.

5918427278 Bluetooth: Host: Make bt_le_addr_is_bonded public
Some GATT services and profiles define specific behavior
based on whether the remote device is bonded or not.
The internal function, bt_addr_le_is_bonded, is the
only function to do this, but it was kept internal,
and could thus not be used for those services
without including hci_core.h.

The function has been moved to the public API
so that application can determine if a remote
address is bonded or not, and has been renamed
to not use the bt_addr namespace, but rather the
bt_le.
