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.
