Revert "Add DocsUI Support for Focal Length/ISO"

This reverts commit c6678536.

Reason for revert: https://b.corp.google.com/issues/64373356

I've verified locally that this CL causes the bug. But on the surface I can't tell how. Since this is blocking enabling presubmit on master, reverting. We can work out the cause later today and resubmit.

Test: Presubmit (small and medium) passing locally.
