Revert of bluetooth: android: Initial Low Energy Discovery Sessions. (patchset #9 id:320001 of https://codereview.chromium.org/1150833002/)

Reason for revert:
Downstream Chrome build encountered runtime errors:

Original issue's description:
> bluetooth: android: Initial Low Energy Discovery Sessions.
>
> Add ability to start a low energy scan, though do nothing with the
> results for now besides log that they are found.
>
> Rename hasBluetoothPermission -> hasBluetoothCapability because the
> permissions, SDK version, and hardware feature must all be present.
