c0fbfc3bb8 Bluetooth: Controller: Fix drift compensation on connection update
Fix drift compensation applied late under high throughput at
after the instant has passed for a connection update.

Workaround test failures due to Zephyr Controller scheduling
overlap causing Periodic Advertising Sync timeouts, ACL
connection failed to be established or Controller assertion
when having latency at the CIS setup instant.

Workaround by using `-start_offset` to ensure that the ACL
established does not overlap the sink being established.

58091b181f Bluetooth: Controller: Fix conn timeout due to delayed conn upd ind
Unlike legacy Zephyr Controller's double headed Tx queue
linked list, the new split Zephyr Controller's new LLCP does
not place a control PDU at the head of the Tx queue causing
control PDUs to be delayed on air.

Pause the data enqueue until pending PDUs are transmitted
across before enqueuing LE Connection Update Ind PDU, and
thereafter resume other PDUs being enqueued again.

There can still be connection timeout if enqueued PDUs are
not being transmitted/acked during repeated retransmissions.

Updated bap_unicast_audio_acl_disconnect test to not use
random seed, to be similar to unicast_client test; to get
it to pass without overlapping state/roles casing connection
failed to be established after the changes in this PR.

Single timer use needs additional event overhead to start
radio to ensure the software switch implementation executing
