Add `pre_delete_option` filter

[flixos90]

get_option() and update_option() already have filters to short-circuit their respective processes, so I think a similar filter should be added to delete_option() as well.

37929.diff​ is a first take on introducing the filter.

Interesting idea.

In your patch, maybe you should use

! is_null( $skip )

instead of

null !== $skip

to keep it consistent with the null check immediately below.

37929.2.diff​ is an updated patch that gives parity with the latest patch on #37928.
