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.

JIT: Update invalid opcache.jit INI value message to include "tracing" and "function" values
...
`opcache.jit` accepts `tracing` and `function` as aliases, but they were not mentioned in the start-up INI warning message.
This updates the error message to include all possible values.
Closes GH-6490.

While the use of zend_cpu_supports_*() is only strictly necessary
inside ifunc resolvers, where the cpu state has not been initialized
yet, we should prefer the compiler builtins in all cases.
