…#19029)

Have each of the specialized methods for registering a constant return a
pointer to the registered constant the same way that the generic
`zend_register_constant()` function does, and use those in the generated
arginfo files to avoid needing to search for a constant that was just
registered in order to add attributes to it.
…hecks (#18995)

* Zend: Add `zend_check_method_accessible()` to DRY method visibility checks

* Zend: Add assertions verifying flags didn't change before `zend_check_method_accessible()`

* Try `zend_always_inline` for `zend_check_method_accessible`
Instead of using lookup tables, we can use a combination of shifts and
byte swapping to achieve the same thing in less cycles and with less
code.
