Bluetooth: controller: Framework for new feature BT_CTLR_JIT_SCHEDULING

Browse source 
This option enables BT_TICKER_SLOT_AGNOSTIC which eliminates
priorities and collision resolving in the ticker.

Event scheduling states are stored in the lll_hdr, and event priority
is passed from LLL implementation, and runtime priority calculated.

LLL implementation decides whether to program radio, start preemption
timer, and/or queue prepare in the prepare pipeline.

Event arbitration is made possible via the common LLL, but not yet
implemented in Nordic LLL.

This option enables the experimental 'Next Generation' scheduling
feature, which eliminates priorities and collision resolving in the
ticker, and instead relies on just-in-time ("lazy") resolution in
the link layer.
