Move all API related annotations into annotation_key_constants.go

Separate from #45869. See #45869 (comment) for details.

This PR does nothing but move constants around :)

@caesarxuchao Sorry, the failure is hack/.linted_packages. The stale entry (pkg/api/annotations) is removed now.

For approval :)

(This is blocking #45869.)

[thockin]

[thockin]

[MrHohn]

Thanks! Yeah we could do that later :)
