When removing a CIG, the instance and associated CIS instances were not
always released. This causes repeated Create_CIG/Remove_CIG operations
to fail assertion with resource error.

Fixes issue #53301.

New LLCP will process the CIS establishement in the TX path, meaning it
will only process once every ACL connection interval.
If ACL connection interval is significantly longer than the ISO
interval, CIS packets corresponding to the ACL connection interval will
be lost. This may cause latency in audio rendition.
By processing the CIS establishment in the RX path, notification will be
sent immediately, and audio path is enabled fast to reduce latency.
When a CIS fails to establish, the controller shall complete the
procedure by sending a CIS_ESTABLISHED event containing the error.

When the 'instant' of a CIS is postponed by increasing the conn_event of
the CIS_RSP compared to CIS_REQ, the CIS offset shall be calculated as
an equivalent window offset by an integer number of ISO intervals.
This is obtained by increasing the CIS_Offset_Min and CIS_Offset_Max by
the modulus of the connection interval delay time.

To be able to timely start the first CIS/CIG, if the requested instant
is the next connection event, call ull_peripheral_iso_start directly
from rp_cc_state_wait_rx_cis_ind instead of waiting for next time
through the state machine.
To enable ULL/LLL to prevent adding latency when LLCP is waiting for
instant, local- and remote procedures with instant now expose a function
for checking this state.
