Fix missing nRF CCM disable on connection event abort.
There can be a problem on nRF SoC for example when a S8
"encrypted" reception is aborted, and a 2M "cleartext"
reception starts; slow CCM (that is not stopped as part of
radio disable) will corrupt a fast received "cleartext" when
the same current free rx buffer is reused in the Controller.

on a faster PHY than the abort-er.

Fix Central CIS offset calculation for dissimilar ACL and

Mayfly execution of `mfy_cig_offset_get()` could be after
"LLL Prepare" or before depending on whether a previous radio
event is being preempted or not, respectively; the
`conn->lll.event_counter` may not be pre-incremented.
This race condition is fixed by the fact that we use a
constant instant delta value now.
Dissimilar ACL and ISO intervals may lead to ACL overlapping
or be too close to ISO event, causing preemption; under this
case ACLs "LLL Prepare" would run after `mfy_cig_offset_get`
causing incorrect calculation of CIS offset without the fix.

structure as a constant CIS Create instant delta is now

Update all HCI drivers to use the new H:4 encoding for buffers passing

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
