Introduced a unified definition for HCI packet type indicators in
'bluetooth/hci_types.h. This change streamlines the code in
'drivers/bluetooth/hci/', reducing redundancy.
Enhances maintainability and consistency across all HCI drivers.

`bt_recv` is invoked from the BT long work queue, which is preemptible.
The host uses cooperative scheduling to ensure thread safety.

In the case that there are no more ISO buffers left,
"No available ISO buffers" is logged. However, given the
nature of ISO where we are (very) likely to get additional ISO
very soon after (typically every 7.5 or 10ms for audio),
this will get logged a lot, and the logging may in some
cases actually prevent the application from handling and
freeing existng buffers due to the immense logging,
which may make this (minor) issue into a blocking issue.
This is fixed by reducing the logging to the first
occurence, and then only every 100 afterwards, which has
shown to reduce the risk of this effectively blocking
the application.

The existing driver and sample:
- drivers/bluetooth/hci/rpmsg
- samples/bluetooth/hci_rpmsg
are no longer correctly named, since they now use the IPC subsystem to
send and receive data. The IPC subsystem can use RPMsg as a transport,
but that is one of several selectable backends.
I initially wanted to deprecated both the BT_RPMSG Kconfig option as
well as the zephyr,bt-hci-rpmsg-ipc chosen node in Devicetree. However,
this proved to be undoable in the case of the Kconfig option. This is
because it's a choice option, and those have special behavior. In
particular, the only practical way to deprecate would've been to keep
the old Kconfig option outside the choice (much like it's done in this
commit) but then also add a 'depends on !BT_RPMSG' on each of the
remaining choice symbols *except* on the new BT_HCI_IPC one. This, however,
only works correctly for .conf files. If a board instead sets the
default BT_HCI_BUS_TYPE in the Kconfig.defconfig file then the Kconfig
tree parsing would fail, because it'd try to set it to a value
(BT_RPMSG) that is no longer part of the choice.
