7349c8572d Bluetooth: Shell: BR: Set user data size for rfcomm tx pool
The user data size of the RFCOMM tx pool is zero. There is not enough
space to put the tx_meta data. Use CONFIG_BT_CONN_TX_USER_DATA_SIZE to
set the data size for the RFCOMM tx pool.

f7bae12cef bluetooth: smp: Fix build warnings for central with OOB legacy only
Currently, there are build warnings that are triggered when building
for BT central and legacy OOB pairing only:
CONFIG_BT_SMP_OOB_LEGACY_PAIR_ONLY=y
CONFIG_BT_CENTRAL=y

There was a PR that handled this issue in the past https://github.com/zephyrproject-rtos/zephyr/pull/74400.
Unfortunately, this PR even though it fixed the warnings it also
broke the BT peripheral and legacy OOB pairing only build:
CONFIG_BT_SMP_OOB_LEGACY_PAIR_ONLY=y
CONFIG_BT_PERIPHERAL=y

https://github.com/zephyrproject-rtos/zephyr/pull/82552 was merged in
order to fix the issue with the peripheral build configuration.
Unfortunately, this PR reintroduced the warnings for BT central and
legacy OOB pairing.

This commit brings changes to make sure that both the BT central and
peripheral builds with OOB legacy pairing are buildable and
warnings free.

Also in this commit, a new build test case is added for the BT central
and legacy OOB pairing along the existing BT peripheral test case

In current implementation, the SDP response packet will be ignored if

c2488fdd30 bluetooth: buf: Add a callback for freed buffer in rx pool
The Bluetooth data buffer API currently lacks a mechanism to notify when
a buffer is freed in the RX pool. This limitation forces HCI drivers to
adopt inefficient workarounds to manage buffer allocation.

HCI drivers face two suboptimal options:

- Blocking calls: Use bt_buf_get_rx with K_FOREVER, which blocks the
  execution context until a buffer becomes available.
- Polling: Repeatedly call bt_buf_get_rx with K_NO_WAIT, which increases
  CPU load and reduces efficiency.

This commit introduces a callback mechanism that is triggered each time
a buffer is freed in the RX pool. With this feature, HCI drivers can:

- Call bt_buf_get_rx with K_NO_WAIT.
- Wait for the callback notification if a NULL buffer is returned,
  avoiding unnecessary polling.

The new callback improves efficiency by enabling event-driven behavior
for buffer management, reducing CPU overhead while maintaining
responsiveness.

b3ffaf4441 Bluetooth: Host: Cancel pending deferred work on disconnect
This fixes an issue that occurred if deferred_work is queued by another
procedure before we run bt_conn_set_state(BT_CONN_DISCONNECTED).
bt_conn_set_state yields to the system work queue in bt_conn_tx_notify,
and then deferred_work runs and handles the disconnected callbacks.
bt_conn_set_state then enqueues another deferred_work which calls the
disconnected callbacks again and causes an assert. k_work_cancel_delayable
will clear queued deferred work when we call
bt_conn_set_state(BT_CONN_DISCONNECTED), guaranteeing that the disconnect
callbacks will only be called once.

66ff97e69b Bluetooth: Host: Deprecate BT_BUF_ACL_RX_COUNT symbol
Because the number of ACL RX buffers must be at least the number of
maximum connections plus one, increasing `CONFIG_BT_MAX_CONN` could
inadvertently lead to a build failure if the number of ACL RX buffers is
not also increased. This dependency may not be obvious to users.

To address this issue, this commit deprecates the
`CONFIG_BT_BUF_RX_COUNT` Kconfig symbol and computes the value in
`buf.h` using the new `BT_BUF_RX_COUNT` define. Note that the default
value and the minimum range value have been changed to 0 to "disable"
the option.

Additionally, to allow users to increase the number of ACL RX buffers,
this commit introduces the new `CONFIG_BT_BUF_RX_COUNT_EXTRA` Kconfig
symbol. The value of this symbol will be added to the computed value of
`BT_BUF_RX_COUNT`.

The configurations of tests and samples have been updated to reflect
