Adjust how `replace-match' runs modification hooks

* src/editfns.c (Fsubst_char_in_region)
(Ftranslate_region_internal):
* src/cmds.c (internal_self_insert): Update callers.
* src/insdel.c (replace_range): Allow inhibiting
signal_after_change/update_compositions.
* src/lisp.h: Update.

* src/search.c (Freplace_match): Run the modification hooks at the
end instead of before adjusting point (bug#42424).
