SL-12005, back out SRGB changes for projector spotlights

Deferred spotlights were transitioned srdb->linear in commit 653133b
The lights transition between the deferred and (some other) path at fixed camera
distance, causing a distinct light-level pop. Backing out this change to avoid
the pop. Note to the future: pick a light space at the beginning and stick with it.
