In order to bring consistency in-tree, migrate all drivers to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to #45388 for more details.

In order to get rid of the duplication of the code that we had until now
in the tree, consolidate the handling of multiple calls to
bt_hci_cmd_send_sync(BT_HCI_OP_LE_RAND, ...) in a single location,
namely in hci_core.
This allows all of the users of this HCI command to use a single
implementation of the iterated sending of the HCI command to fill a
buffer with random bytes.

bt_hci_cmd_send_sync() requires the caller to unref the buffer that is
sent back as a response. Add the missing call to net_buf_unref()
accordingly.

Adds an entropy driver that uses Bluetooth HCI commands as its source
of randomness. As this method is blocking, the ISR API is not supported.
As this method will range from relatively slow (same core Bluetooth HCI
controller) to extremely slow (UART HCI Bluetooth controller), use the
xoshiro PRNG by default for RNG generation.
Implements #37186
