Derive BT_CTLR_ISO_TX_BUFFER_SIZE from BT_ISO_TX_MTU to have
optimal Controller memory allocations.
BT_CTLR_ISO_TX_BUFFER_SIZE can be set lower than
BT_ISO_TX_MTU in which case upper layer can send fragmented
SDU to the Controller.

Increase the timeouts to be 60 instead of 6.
The reason for this is that some controllers (like the Zephyr
controller) will reserve some of these to ensure stability,
and in fact with skip = 5 and retry = 6, it would still
send the PA reports at every interval.
To accomodate a higher timeout value, the functions used to
convert PA intervals to PA timeouts have been updated.

The defines from the Bluetooth Audio assigned numbers are not
specific for LC3. This commit removes the LC3 infix and
the reference to LC3 in the documentation for them.
It also cleans up some of the documentation and
names of the enums.

Why?
- metadata is easier to manage as an array + index
- less error-prone -> less memory-management bugs
- we can. because of the previous refactor
- PDU allocations are more predictable
- ATT buffer size can be optimized by app
- isolates ATT from the rest of the ACL users
- decouples ATT PDU size from e.g. SMP w/ LESC
Drawbacks:
- higher memory usage
- kconfig change
The higher memory use is only temporary, as this will be followed-up
with more refactors that should bring it back down.

This removes the fixed size bt_bap_base, which provides
2 improvements:
1) The RAM usage of the broadcast sink has been reduced.
For the Broadcast Sink sample it is a reduction of 120
octets, but with much better scaling for supporting
more or larger BASEs.
2) The functions to parse BASEs now support arbitrary sized
BASEs, where they were previously restricted by our
local Kconfig options. This allow us to parse any BASE
from a remote device, without encounting memory issues.
We are still memory restricted on the devices we
actually want to sync to.

Instead of forcing use of NEWLIB_LIBC, select any available complete C
library implementation. Add CONFIG_REQUIRES_FLOAT_PRINTF and adjust
CONFIG_LIBC_MALLOC_ARENA_SIZE as needed.

There is no reason why the capabilities
should be modified by the stack after registration,
nor any reason why a the unicast client application
needs to modify the reported remote capabilities, so
all have been marked as const.

Refactor the bt_audio_codec_cap to use flat arrays to store
metadata and codec specific capabilities.
The purpose of this is to make it easier to copy the data
between layers, but also to support non-LTV data for non-LC3
codec capabilities.

The broadcast sink API has been modified so that all scanning, etc.
will be done by the application, rather than the stack. This commit
updates the sample to use this updated API.

Add two TMAP broadcast sample applications.
tmap_bms implements the Broadcast Media Sender role. It uses CAP
Initiator broadcast APIs to broadcast an audio stream.
tmap_bmr implements the Broadcast Media Receiver role. It scans and
syncs to the PA having filtered the EA by the presence of TMAP role
information. It also instantiates the VCP.
