Bluetooth: Controller: Review rework of jitter in aux offset

Review rework of the fix to remove the jitter in aux offset
and sync offset values.

Force select BT_TICKER_REMAINDER_GET and BT_TICKER_LAZY_GET
features when Extended Advertising and Periodic Advertising
is supported.

Rename ticks and microsecond offset value struct members
for primary PDU event offset (to auxiliary PDU event).

Converted HAL_TICKER_REMOVE_JITTER and HAL_TICKER_ADD_JITTER
macro to functions.
