Enable deprecation checks for removed settings (#53317)

Today we do not have any infrastructure for adding a deprecation check
for settings that are removed. This commit enables this by adding such
infrastructure. Note that this infrastructure is unused in this commit,
which is deliberate. However, the primary target for this commit is 7.x
where this infrastructue will be used, in a follow-up.
