Fix deferred Connection Update offset population by
introduction of explicit states waiting for the offset
calculation to complete in the ULL_LOW context.
Fixes#29636.
The problem was, in an encrypted connection the enqueued PDU
to be transmitted is encrypt in the prepare callback by the
hardware and swapped to a different buffer for transmission;
the deferred offset population did not reflect in the
transmitted PDU as it was filled in the cleartext buffer
while encryption completed into the encrypted buffer.

lll->conn is only defined valid when BT_CENTRAL is enabled.
Also ull_sched_mfy_after_mstr_offset_get is only used when BT_CENTRAL
is enabled.

Port advanced scheduling implementation from legacy
controller.
This implementation schedules
- non-overlapping scan window when there are simulataneous
central connections active
- central connection establishment with similar connection
intervals be placed in a non-overlapping group, temporally
- connection parameter request with calculated window offset
hints to have non-overlapping BLE radio events.

This is a squash merge of commits introducing the new split
Upper Link Layer and Lower Link Layer architecture of the
Bluetooth Low Energy controller.
This introduces a new, improved Link Layer based on the
concept of split responsibilities; The Upper Link Layer
(ULL) is in charge of control procedures, inter-event
scheduling and overall role management. The code for the
ULL is shared among all hardware implementations. The
Lower Link Layer (LLL) is responsible for the intra-event
scheduling and vendor specific radio hardware access.
The communication between ULL and LLL is achieved through
a set of FIFOs that contain both control and data packets.
