When using the LLEXT buffer loader we now avoid copying extensions
from storage to allocated memory by pointing directly into the stored
image. We then also perform linking and relocation in that memory,
which modifies its contents. However, this is impossible if that
storage is read-only. Add a Kconfig flag to distinguish between
writable and read-only storage types. Also use that flag to decide,
whether the extension image in test_llext_simple.c should be defined
as const or not.

Extend the llext_load() / llext_unload() API to let it be called
repeatedly for the same extension to increment or decrement its
reference counter respectively. We use a mutex to protect the counter
and make both llext_load() and llext_unload() return the use-count to
let the caller identify when the first loading and the last unloading
took place.

Loadable modules can contain global (not "static") functions, even if

Fix the possible race between TCP work items already scheduled for
execution, and tcp_conn_unref(), by moving the actual TCP context
releasing to the workqueue itself. That way we can be certain, that when
the work items are cancelled, they won't execute. It could be the case,
that the work item was already being processed by the work queue, so
clearing the context could lead to a crash.
Remove the comments around the mutex lock in the work handlers regarding
the race, as it's not the case anymore. I've kept the locks however, as
they do make sense in those places.

EATT is the only user of `bt_l2cap_chan_send_cb`, and not necessary. We
can maintain the same functionality without it.
Instead of passing and storing the callback into l2cap, we can store it
in a callback queue in the ATT bearer struct.
This will allow us to remove that internal API later, in order to
streamline the l2cap API.

The Zephyr's core ethernet code had to be adjusted to support setting T1S
PLCA parameters from user Zephyr programs.
Such approach allows more flexibility, as T1S network configuration;
especially PLCA node numbers, can be assigned not only via device tree
at compile time. For example user can read them from EEPROM and then
configure the network accordingly.
For now - the union in struct ethernet_t1s_param only consists of plca
structure. This can change in the future, when other T1S OA parameters -
like Receive/Transmit Cut-Through Enable (bits RXCTE/TXCTE in OA_CONFIG0
register) are made adjustable from user program.

This commits adds the LE API's for the LE Power Control Request Feature
in Zephyr.
The support of feature is provided with the controller-based feature
selection with BT_CTLR_LE_POWER_CONTROL_SUPPORT and is selectable via
BT_TRANSMIT_POWER_CONTROL.
With the new APIs, the applications will:
get improved reading of local and remote tx power
be aware of changes in remote or local tx power
Defined HCI commands in Core Spec v5.4:
7.8.117 LE Enhanced Read Transmit Power Level command:
improvement to existing local tx power reading.
7.8.118 LE Read Remote Transmit Power Level command:
Remote tx power is read through an event (LE Transmit Power Reporting)
7.8.121 LE Set Transmit Power Reporting Enable command:
Enables local or remote tx power reporting to monitor changes in tx power
7.7.65.33 LE Transmit Power Reporting event
Note: to utilize the Feature fully Nordic-LL-only vendor-specific commands
are needed. These will not be added in RTOS zephyr but instead
implemented in a maintainable way in sdk.
