Introduce Controller dependent EVENT_MAFS_MIN_US value to
use as the value when populating the aux offset between
Extended Advertising primary and auxiliary channel PDUs.
This can be used as workaround for peers having difficulty
receiving Extended Advertising PDUs with near 300 us MAFS
values used in aux offset calculations.

The BIGinfo PDU bitsets were not accessed in a portable maner for
endianness independence, and need to be handled as bit-manipulations.
Add utility functions to access PDU bitset variables independent of
endianness. Use macros to abstract the offsets and widths.
Conversion of BIG_Handle to LE in HCI layer incorrectly use
sys_cpu_to_le16, which fail because target type is 8-bit.

Fix missing offset adjust field assignment in the Periodic
Advertising's sync_info struct that is present in the
Extended Advertising PDU.
When the sync offset is equal or over 2.4576 seconds from
the Extended Advertising PDU, then the sync offset has to
be reduced by 2.4576 seconds and the offs_adjust flag be
set in the sync_info field.
This fixes a bug where Periodic Synchronization could not
be established for Periodic Advertisings with intervals
greater than 2.4576 seconds as the sync offset was
incorrect due to rollover in the 13-bit offset field.

If the CTE is attached to data channel packet, the packet must
include information about CTE. The information is stored in
CTEInfo structure that is available in S1 byte of a packet.
Radio checks if the S1 byte is present by verification of
CTE present (CP) bit in byte S0.
The commit add these data to pdu_data structure declaration.
That allows to prepare packet before it is parsed and send
by Radio peripheral.
Besides that there added a new function ull_pdu_data_init that
initlializes fields in pdu_data object that are read only by
lower link layer. CP bit in S0 byte and content of S1 bytes
