Replace the BT_CTLR_ADVANCED_SCHEDULING_CENTRAL_CONN_SPACING
Kconfig with BT_CTLR_CENTRAL_SPACING to configure the
the spacing from the beginning of a central connection event
to beginning of the next central connection when supporting
multiple simulataneous central connections.
If the BT_CTLR_CENTRAL_SPACING in microseconds is smaller
then the required time reservation for a connection event,
for given maximum data length and PHY in use, then the
calculated time reservation will be used as the spacing
between consecution central connection events.
The change fixes an issue wherein use of old Kconfig with
higher values causes new central connections to be placed
in between already connected central role if there was
free time space available to fit the new connections time
reservation.

Explicitly set all bits of used radio registers when
configuring radio events, removing the dependency on having
the power-on reset value and removing the need to ensuring
power-on reset values being set in the radio peripheral.
This will ensure the Controller has radio register value
correctly configured irrespective of changes across SoCs'
radio register power-on reset values.

Program CIG ticker with window widening drift. Introduce vendor specific
conversion macros allowing sub-microsecond resolution in the
accumulation of window widening drift per interval.
Calculation of window_widening_max_us is done for NSE<3, and must be
adjusted in the LLL before use, if the first CIS in the CIG has a
NSE>=3. In that case window_widening_max_us shall be limited to one sub
interval.

Macro that was defined in the `common/log.h` has been moved to the newly

Files that were using those macro has been updated consequently. Also, the

using any logging methods.
Some `#include "common/log.h"` have been removed. Those were required
before when including `hal/debug.h`. With this change, `hal/debug.h` no
longer has this requirement, because the replacement, `common/assert.h`

PDUs (to save memory)
- Introduces lll_adv_aux_data_init, lll_adv_aux_scan_rsp_alloc and
lll_adv_sync_data_init to indicate if the PDU is a primary/legacy PDU
or secondary/auxillary PDU
- Scan response PDUs are initialized later, since the correct pool to draw
from depends on whether the advertising is extended or legacy
