089df60140 bluetooth: esp32: fix VHCI semaphore misuse in HCI send path
The TX flow control semaphore was initialized with a count of 1 and
released again after every bt_esp32_send() call. This broke the VHCI
flow control contract and could allow sending more packets than the
controller advertised.

This prevents host/controller overruns and ensures proper synchronization
with the ESP32 VHCI interface.

8de6705ec3 drivers: bluetooth: Align bt_hci_send behavior on error
This change alignes HCI drivers behavior with Host expectation. That is:
if an HCI driver managed to send a packet to Controller, the HCI driver
also unreferences it. If the HCI driver didn't manage to send the
packet to Controller and returns an error code, it does not unreferences
buffer.

This change aligns the behavior of HCI drivers with the Host's
expectations. Specifically:
- If an HCI driver successfully sends a packet to the Controller, the
  HCI driver also unreferences it.
- If the HCI driver fails to send the packet to the Controller and
  returns an error code, it does not unreference the buffer.

Refactor the controller init to use the new init routines the
controller now provides. Instead of using a hardcoded set of
features, the features are now initialized based on Kconfig
values that the application selects.

Add config files under modules/hal_silabs, used by the controller
init routines in the external module hal_silabs to determine which
features to enable based on Kconfig options. This brings the
controller feature configurability to roughly parity with the
Simplicity SDK.

71ef6c6979 Drivers: Bluetooth: H4: Use a semaphore to wake up HCI RX thread
There is an issue that the buffer cannot be allocated by the function
`read_payload()` in UART ISR context. Then the UART RX will be
disabled. The H4 driver hopes to get the receive buffer in the HCI RX
thread and then open the UART RX again. However, there is a situation
where the HCI RX thread is blocked in getting the received data
buffer. However, since the UARt RX has been disabled, the HCI RX
thread cannot get the received data buffer. Therefore, the RX thread
is always blocked here, causing the Bluetooth host to not work
properly.

Add a semaphore `rx.ready` to notify new received data buffer has
been added to H4 RX queue.

Wait for the semaphore `rx.ready` instead of H4 RX queue in HCI RX
thread.

Wake up the HCI RX thread when failing to allocate the RX buffer.

6113230ce3 Bluetooth: drivers: Update to use new H:4 buffer encoding
Update all HCI drivers to use the new H:4 encoding for buffers passing
to/from drivers.

One behavioral change that's done in favor of simplicity, is that where
there's previously been switch statements that could return an error for
unsupported packet types now simply pass any received packet unchanged to
lower layers of the controller (or the HCI transport). Handling this is
now the responsibility of the lower layers, however in practice hitting
such scenarios means that there's a mismatch between configured host and
controller features.
