Remove Crop Image from Conpherence Edit UI

Summary: Ref T11730. Removes the front end crop feature. Will follow up with proper removal, but this seems broken outright.

Test Plan:
Edit a room, don't seen "Crop" feature. Upload new photo, works fine.

- grep for `ConpherencePicCropControl`
- grep for `aphront-crop`
