Fix potential memory leak in XPath evaluation results

[RFC] Improve callbacks in ext/dom and ext/xsl (#12627)

[RFC] DOM HTML5 parsing and serialization support (#12111)

Cover more paths in dom_xpath_ext_function_php() with tests

Also removes an incorrect comment: we *do* need the special namespace
node handling code, otherwise we'd segfault.

Use zend_result as return for properties in ext/dom (#12113)

Preallocate result array size in xpath (#12105)

We know what size they're going to be, and we know they are packed
arrays. Prevent reallocations and initialisation overhead by setting the
initial size and initializing it as packed from the start.

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.

Promote warnings to error in DOM extension

Consolidate new union type ZPP macro names

They will now follow the canonical order of types. Older macros are
left intact due to maintaining BC.

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.

Remove spurious return true from DOMXPath::registerPhpFunctions()

Only one of three identical cases returned true, and the function
is documented to return void. Remove the outlier.

Use string|array type in DOMXPath::registerPhpFunctions()

Remove no_separation flag

Disallow separation in a number of callbacks

All of these clearly do not need separation support.

This macro is trivial, it's more obvious to use ZEND_THIS directly.
