More horrible 515 proc compatibility. (#71333)

So i left over some basic `/whatever/proc/format` uses in the original
PR this fixes it.

Notable exceptions to the rule:
- Paths in add_verb/remove_verb, we need full path instead of a name
there to access verb metadata so we can't use proc ref macros there.
- regex.Replace, found out that it does not accept call by name. Instead
i added new REGEX_REPLACE_HANDLER so we can at least try to mark these.

There's still leftover global procs that do not use GLOBAL_PROC_REF but
they functionally equivalent so that's for later.

I don't see any reasonable way to grep for this. But if you got any
ideas please share.
