Keep JIT region executable under ZTS
When one thread tries to compile a script, another thread may
already be executing JITed code. In this case we can't make the
memory non-executable.
This violates the W^X principle, but doesn't seem to be avoidable
for ZTS builds for now. The same problem does not exist for NTS,
as it's a different process executing there, which has it's own
memory protection mapping.
Closes GH-6595.
