Fix GH-11347: Memory leak when calling a static method inside an xpath query

It's a type confusion bug. `zend_make_callable` may change the function name
of the fci to become an array, causing a crash in debug mode on
`zval_ptr_dtor_str(&fci.function_name);` in `dom_xpath_ext_function_php`.
On a production build it doesn't crash but only causes a leak, because
the array elements are not destroyed, only the array container itself
is. We can use the nogc variant because it cannot contain cycles, the
potential array can only contain 2 strings.

Closes GH-11350.

Implement named parameters

From an engine perspective, named parameters mainly add three

Implement named parameters

From an engine perspective, named parameters mainly add three
concepts:

* The SEND_* opcodes now accept a CONST op2, which is the
argument name. For now, it is looked up by linear scan and
runtime cached.
* This may leave UNDEF arguments on the stack. To avoid having
to deal with them in other places, a CHECK_UNDEF_ARGS opcode
is used to either replace them with defaults, or error.
* For variadic functions, EX(extra_named_params) are collected
and need to be freed based on ZEND_CALL_HAS_EXTRA_NAMED_PARAMS.
