The API name space for Bluetooth is bt_* and BT_* so it makes sense to
align the Kconfig name space with this. The additional benefit is that
this also makes the names shorter. It is also in line with what Linux
uses for Bluetooth Kconfig entries.
Some Bluetooth-related Networking Kconfig defines are renamed as well
in order to be consistent, such as NET_L2_BLUETOOTH.

For whitelist and resolving list handling, avoid trying to start the

Additionally, and since simultaneous scanning and initiating is not

disabling scanning.

As a preparation for advanced filtering (Controller-based privacy) this
commit refactors whitelisting so that it becomes its own module and
actually correctly performs state tracking to avoid modifying the
whitelist when it's in use.
Additionally it also removes the duplicate separate entries for
advertising and scanning, since the specification only allows one single
global whitelist singleton.

Added support for Bluetooth v5.0 PHY Update Procedure in the
Controller.
Asymmetric PHY connections do not work for now due to the
Radio mode not being setup in time in the ISR during tIFS
period and the Radio already ramping up in the cached
previous Radio mode to meet tIFS deadline.
Subsequent commits will add this feature, by either double
buffering the mode in software or using fast radio ramp up
which gives enough time in the ISR to change the mode.

The Bluetooth Specification allows for optional Controller to Host flow
control based on the same credit-based mechanism as the Host to
Controller one. This is particularly useful in 2-chip solutions where
the Host and the Controller are connected via a physical link (UART, SPI
or similar) where the Host is sometimes required to ask the Controller
to throttle its data traffic while still making sure that relevant
events get through the line.
This implementation is based on a simple queue of pending events and
data that is populated whenever the Controller detects that the Host is
out of buffers and then emptied whenever the Host notifies the
Controller that is ready to receive data again. Events relevant to the
connections are also queued to preserve the order of arrival.
At this point the Controller ignores the connection handle sent by the
Host and treats all connections equally, and it also queues events even
for connections that have no data pending in the queue. Both this items
can be improved if necessity arises.
Note that Number of Completed Packets will still flow freely from the
Controller to the Host regardless of the pending ACL data packets, which
might lead to inconsistencies in the sequential order of certain
operations that include bi-directional data transfer.
