Update Bluetooth API annotations.

Recent work has introduced a new "Nearby devices" runtime permission
which protects all existing Bluetooth APIs; we've done this by
defining a <split-permission> to convert the old BLUETOOTH and
BLUETOOTH_ADMIN permissions into one of three new permissions:

* BLUETOOTH_ADVERTISE: Required to be able to advertise to nearby
                       Bluetooth devices.
* BLUETOOTH_CONNECT:   Allows applications to connect to paired
                       bluetooth devices.
* BLUETOOTH_SCAN:      Required to be able to discover and pair
                       nearby Bluetooth devices.

At its core, this change begins updating the Bluetooth APIs to have
correct @RequiresPermission indicating which permission is actually
enforced internally.  To ensure alignment across Binder, the newly
added "RequiresPermissionChecker" Error Prone checker was used to
discover any inconsistencies, ensuring correctness from server-side
enforcement up through to the public APIs.

In addition, since developers will continue building apps for both
modern and legacy platforms, this change introduces new auto-doc
annotations which will emit helpful consistent documentation
describing the behavior of older devices that are still using the
old permission model.
