The execution time of k_sem_give() increased slightly recently, and
since it was being called from the radio ISR this had an impact in the
deadlines not being met.
This change moves the actual call to k_sem_give() to a lower-priority
job and thus out of the ISR to avoid its execution time affecting the
ISR's timing.

Reduce the time limit for active clock startup and increase
the CPU usage time limit before hard real-time radio
transmit/receive.
Due to isr_wrapper overhead in ARM architectures, more time
was used before hard real-time radio transmission or
reception which was detected by controller implementation
and the controller aborted the radio transactions.
This commit permits more CPU utilization by the controller
before hard real-time radio transactions start.

On CPUs like nRF51 which run at 16MHz, certain BLE control
procedure PDU processing take more CPU time than permitted
inside tIFS (150us). Current implementation of Data Length
Update procedure does not span over multiple connection
interval (unlike Encryption Setup, which is another control
procedure processing that would consume more CPU time)
hence taking more CPU time inside tIFS on nRF51.
During the radio ISR, the active clock and packet timer are
active and it is used to profile the CPU time taken which
is used to decide on whether there is sufficient time in
the current radio event to process the control packet.
This commit also fixes a potential bug that would cause
disconnection due to MIC failure on encrypted connections
that performed Data Length Update. Controller used to NACK
the request/response PDU if it was not in a state to resize
the receive buffers but did not reset the CCM counter. This
is now fixed by the change done to NACK control PDU based
on available CPU time in radio ISR.

When the Controller is configured to support less than 251
as the supported maximum data length, missing check caused
the Controller to incorrectly re-initialize its rx buffers
causing assert during the DLE procedure. This commit fixes
the procedure to correctly use the supported maximum length
if the peer requests a transmit length that exceeds the
supported receive length.

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.

assertions that happen in the Link Layer code are not visible
to the Host which is running on another HCI and connected via
UART or USB to it. This patch allows the Controller code
to output the assertion line number when in such a configuration,
allowing the Host to view the event to help debugging.
The event format used is temporary and will be replaced by a
standardized Vendor Specific specification to come at a later
time.

PDUs received, it will issue an LL_UNKNOWN_RSP PDU to let the

an LL_FEATURE_REQ and _RSP pair.
