Intent is to pass Ellisys ISOAL quality tests for framed TX scenarios
where the TX SDU includes a time stamp that is not based on the
controller's clock.
Changes:
-- Include controller's reception time as a separate field in the TX SDU
information
-- Include decision on whether SDU time stamp is valid and based on the
controller's clock
-- Arbitrate and select / compute time stamp for the SDU

Changes:
-- Disregards target event after segmenting the first TX SDU and instead
decide event based on the next payload and feasibility to fragment
for that event (time-offset > 0)
-- Corrected error SDU release logic when an error occurs while
expecting the start of a new SDU, to avoid releasing an SDU which
could be received in the next payload or event
-- Included additional debug logging

Use the HAL event clear function to clear the RTC EVENT
instead of accessing the register directly.
This allows using an updated version of the RTC HW models
which generate level interrupts (as the real HW) and in
which if the EVEN register is not properly cleared,
the interrupts are kept high, resulting in the interrupt
handler reentering immediately after exiting.

The CIS Central uses the algorithm described in BT Core 5.4 Vol 6,
Part G, Section 2.2 to calculate the Max_PDU value for framed mode.
However, HAP needs the Max_PDU to be calculated according to "Core
enhancement for ISOAL CR" coming with the "Atlanta" update. With this
update, the fragmentation is controlled via a parameter at CIG creation.
Enabling CONFIG_BT_CTLR_CONN_ISO_AVOID_SEGMENTATION will set the
ISO_Interval to 7.5 ms for a 10 ms framed CIG, and calculate Max_PDU to
45/65 for 16/24 kHz.
