regcomp: handle cloning the rexc cleanup in the scope stack
Previous on Win32 this could cause a double-free of the RExC state if
an emulated fork was done with the free of the state on the scope
stack.
Use a custom save type and prevent freeing in the cloned process to
prevent the double-free.
Fixes #23022

Log Message:
-----------
regcomp: ensure the RExC_state freed earlier rather than later
388bf71 (ignoring #23022 for now) ensured that the RExC_state
and its controlled pointers were freed once and only once,
regardless of whether re_op_compile() returned normally or threw
an exception.
Unfortunately that free could happen very later, surviving well beyond
when the regexp was compiled.
Add an ENTER/LEAVE pair to ensure the cleanup is done immediately
on a normal return.
