[PATCH v2] libcamera: pipeline: uvcvideo: Report new AeEnable control as available

[Barnabás Pőcze]

The `AeEnable` control is handled by the `Camera` class directly, but it
still has to be added because `ControlInfoMap`s are not easily modifiable.

See 338ba00e7abfe8 ("ipa: rkisp1: agc: Report new AeEnable control as available")
for more details and a similar change in rkisp1.
