chore: remove @[simp] from List.getLast_eq_iff_getLast_eq_some ( #5178 )
...
This was not a great simp lemma, and hurts simp confluence. Better to
just use it locally where it is useful.
Similarly `List.head_eq_iff_head?_eq_some`.

chore: cleanup #5167 workarounds after update stage0 ( #5175 )

to staging issues. This PR cleans up these workarounds.

feat: allow users to disable simpCtorEq simproc ( #5167 )
...
`simp only` will not apply this simproc anymore. Users must now write
`simp only [reduceCtorEq]`. See RFC #5046 for motivation.
This PR also renames simproc to `reduceCtorEq`.
close #5046
@semorrison A few `simp only ...` tactics will probably break in
Mathlib. Fix: include `reduceCtorEq`.

This should resolve nearly all of the simpNF lints. This is a follow-up
to #4620 .
