Zend/zend_type_code: remove hard-coded integer values and

Browse Source 
remove unused macro ZEND_SAME_FAKE_TYPE
Zend/zend_variables: add _Static_assert on the size zend_rc_dtor_func
_Static_assert is C11, but has been supported since GCC 4.6.

Also removing the comment about keeping those values in sync with
`zend_variables.c` which was obsoleted by commit 0460420205
(designated initializers).

Closes GH-10714.
