Bluetooth: Controller: Kconfig to permit periodic sync event skip

Browse source 
When AUX_ADV_IND or AUX_CHAIN_IND auxiliary channel PDU scan
radio event overlaps Periodic Sync radio event in unreserved
time space, let the Periodic Sync radio event be aborted so
that the auxiliary channel PDU can be received to generate
Extended Advertising Reports. Added a new Kconfig to enable
this.

When AUX_ADV_IND or AUX_CHAIN_IND auxiliary channel PDU scan radio
event overlaps Periodic Sync radio event in unreserved time space,
let the Periodic Sync radio event be aborted so that the auxiliary
channel PDU can be received to generate Extended Advertising Reports.
By default we want Periodic Advertising Sync Events to take priority
over any overlapping Extended Advertising Primary and Auxiliary
channel PDU reception in order to not skip Periodic Advertising Report
generation.
But under simultaneous multiple Periodic Advertising Sync support with
small Periodic Advertising Intervals where there will be a lot of
overlapping Periodic Advertising Sync events, it is desirable to
permit Extended Advertising auxiliary PDU reception be allowed in a
round robin scheduling to skip the overlapping Periodic Advertising
Sync event. This permits new Periodic Advertising peers be discovered.
