Add Controller advanced Kconfig options to select IRQ
priorities of the Radio, Ticker's Worker and JOB IRQs.
This will provide an opportunity to have peripheral IRQ's
of higher level than Bluetooth Controller.

Add Kconfig option to enable advanced scheduling in the
controller.
Enable non-overlapping placement of observer, initiator and
master roles in timespace. Uses window offset in connection
updates and uses connection parameter request in slave role
to negotiate non-overlapping placement with active master
roles to avoid slave roles drifting into active master
roles in the local controller.
This feature maximizes the average data transmission amongst
active concurrent master and slave connections while other
observer, initiator, master or slave roles are active in the
local controller.
Disabling this feature will lead to overlapping role in
timespace leading to skipped events amongst active roles.

Added Kconfig option to enable advanced event preparation
feature.
Enables advanced event preparation offset ahead of radio
tx/rx, taking into account predictive processing time
requirements in preparation to the event, like control
procedure handling and CPU execution speeds. Crystal
oscillator is retained between closely spaced consecutive
radio events to reduce the overall number of crystal
settling current consumptions.
This feature maximizes radio utilization in an average role
event timeslice when they are closely spaced by using a
reduced offset between preparation and radio event.
By disabling this feature, the controller will use a
constant offset between the preparation and radio event. The
controller will toggle crystal oscillator between two
closely spaced radio events leading to higher average
current due to increased number of crystal settling current
consumptions.

Restructure the Bluetooth options more logically.
- Both host and controller are now behind the same high level
CONFIG_BLUETOOTH.
- Selecting controller support disables other HCI driver selection, so
the controller isn't in the same list as HCI drivers any more.
- Under the top-level there's a "Custom stack" option, which when
enabled opens up the option of choosing CONFIG_NBLE.
There are various other cleanups and simplifications in this patch as
well, since splitting these up would have been fairly tricky while
making sure all test cases still build.

The bt_driver API was created when Zephyr only had a Bluetooth host
stack, but no controller-side functionality. The only "driver" that
was needed for the host was the HCI driver, and hence "HCI" was
omitted from the name.
With support both for host and controller Zephyr will be getting more
Bluetooth driver types, in particular radio drivers. To prepare for
this, move all HCI drivers to drivers/bluetooth/hci/ and rename the
bt_driver API bt_hci_driver.
