Generated arginfo header files: remove empty zend_function_entry arrays (#15705)

When a class (or enum) has no methods, rather than using an array that only
contains `ZEND_FE_END`, use `NULL` for the functions. The implementation of
class registration for internal classes, `do_register_internal_class()` in
zend_API.c, already skips classes where the functions are `NULL`. By removing
these unneeded arrays, we can reduce the size of the header files, while also
removing an unneeded call to zend_register_functions() for each internal class
with no extra methods.

Fix registration of internal readonly child classes (#15459)

Fix registration of internal readonly child classes (#15459)

Currently, internal classes are registered with the following code:

INIT_CLASS_ENTRY(ce, "InternalClass", class_InternalClass_methods);
class_entry = zend_register_internal_class_ex(&ce, NULL);
class_entry->ce_flags |= ...;

This has worked well so far, except if InternalClass is readonly. It is because some inheritance checks are run by zend_register_internal_class_ex before ZEND_ACC_READONLY_CLASS is added to ce_flags.

The issue is fixed by adding a zend_register_internal_class_with_flags() zend API function that stubs can use from now on. This function makes sure to add the flags before running any checks. Since the new API is not available in lower PHP versions, gen_stub.php has to keep support for the existing API for PHP 8.3 and below.

Fix argument type of simplexml_import_dom (#13170)

It needs to be "object".
This is because first- and third-party extension can register custom
node types using `php_libxml_register_export`. So we don't know upfront
what types can be expected.

This also changes the error to a TypeError everywhere.

Make SimpleXMLElement a RecursiveIterator

Context: https://externals.io/message/108789

This essentially moves the functionality of SimpleXMLIterator into
SimpleXMLElement, and makes SimpleXMLIterator a no-op extension.

Ideally SimpleXMLElement would be an IteratorAggregate, whose
getIterator() method returns SimpleXMLIterator. However, because
SimpleXMLIterator extends SimpleXMLElement (and code depends on
this in non-trivial ways), this is not possible.

The only way to not keep SimpleXMLElement as a magic Traversable
(that implements neither Iterator nor IteratorAggregate) is to
move the SimpleXMLIterator functionality into it.

Closes GH-5234.

Include stub hash in generated arginfo files

The hash is used to check whether the arginfo file needs to be
regenerated. PHP-Parser will only be downloaded if this is actually
necessary.

This ensures that release artifacts will never try to regenerate
stubs and thus fetch PHP-Parser, as long as you do not modify any
files.
