Subject: [PATCH] camera tests: cover async previewSize updates via
 PreviewSizeChanged

New controller test exercises the Android path where create returns
with the iOS-style synchronous previewSize and the event then
revises it once CameraX's SurfaceRequest fires with the negotiated
resolution. Asserts that previewRotationQuarterTurns stays untouched
(events don't carry rotation; rotation is fixed per camera).

33/33 tests in test/camera/ now green.
