Fix #79922: Crash after multiple calls to xml_parser_free()

We must not call `zend_list_delete()` in resource closer functions
exposed to userland, because decreasing the refcount there leads to
use-after-free scenarios. In this case, commit 4a42fbb worked for
typical use-cases where `xml_parser_free()` has been called exactly
once for the resource, because there is an internal zval (`->index`)
referencing the same resource which already increased the refcount by
one. However, when `xml_parser_free()` is called multiple times on the
same XML parser resource, the resource would be freed prematurely.

Instead we forcefully close the resource in `xml_parser_free()`. We
also could decrease the refcount of the resource there, but that would
require to call `xml_parser_free()` which is somewhat uncommon, and
would be particularly bad wrt. PHP 8 where that function is a NOP, and
as such doesn't have to be called. So we do no longer increase the
refcount of the resource when copying it to the internal zval, and let
the usualy refcounting semantics take care of the resource destruction.

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.

Add flag to forbid dynamic property creation on internal classes

While performing resource -> object migrations, we're adding
defensive classes that are final, non-serializable and non-clonable
(unless they are, of course). This path adds a ZEND_ACC_NO_DYNAMIC_PROPERTIES
flag, that also forbids the creation of dynamic properties on these objects.
This is a subset of #3931 and targeted at internal usage only
(though may be extended to userland at some point in the future).

It's already possible to achieve this (what the removed
WeakRef/WeakMap code does), but there's some caveats: First, this
simple approach is only possible if the class has no declared
properties, otherwise it's necessary to special-case those
properties. Second, it's easy to make it overly strict, e.g. by
forbidding isset($obj->prop) as well. And finally, it requires a
lot of boilerplate code for each class.

Closes GH-5572.
