Add --capture-orientation

Deprecate --lock-video-orientation in favor of a more general option
--capture-orientation, which supports all possible orientations
(0, 90, 180, 270, flip0, flip90, flip180, flip270), and a "locked" flag
via a '@' prefix.

All the old "locked video orientations" are supported:
 - --lock-video-orientation      ->  --capture-orientation=@
 - --lock-video-orientation=0    ->  --capture-orientation=@0
 - --lock-video-orientation=90   ->  --capture-orientation=@90
 - --lock-video-orientation=180  ->  --capture-orientation=@180
 - --lock-video-orientation=270  ->  --capture-orientation=@270

In addition, --capture-orientation can rotate/flip the display without
locking, so that it follows the physical device rotation.

For example:

    scrcpy --capture-orientation=flip90

always flips and rotates the capture by 90° clockwise.

The arguments are consistent with --display-orientation and
--record-orientation and --orientation (which provide separate
client-side orientation settings).
