The ticker `ticks_drift` is propagated via the ticker
elapsed callback, in order to provide necessary information
to correctly calculate total elapsed durations by states and
roles that use ticker extensions to mitigate scheduling
collisions by drifting within a permitted window.

Avoid using sizeof to access ULL and LLL struct members.
Based on the alignment requirements of structures, due to
padding between structure members, use of sizeof of previous
struct member to access next struct member is incorrect.
Continue to use explicitly stored parent pointer to access
ULL context. Combine event header and ULL header so that
the parent pointer point directly to the combined ULL
struct.

The ticker 'force' flag is propagated via the ticker elapsed callback,
in order to provide necessary information for collision resolving in the
link layer.

Remove is_enabled flag in LLL of BIS events context, as the
status returned from ticker_stop interface is sufficient to
determine if the Broadcast ISO Sync was established or not.
HCI Command Disallow as reason is to be returned if sync was
not established or sync was loss prior to call of HCI LE
BIG Terminate Command was called.

Implements the ull_sync_iso_setup function which starts the
ticker for ISO sync. Furthermore, ll_big_sync_terminate
will not stop the ticker as well.
