Generated arginfo header files: use known strings for prop names when… (#15751)

Instead of allocating, using, and then releasing a zend_string for every
property name unconditionally, only do so when the minimum supported version of
PHP does not have that string in its known strings (ZEND_KNOWN_STRINGS). If the
string is already known, just use the known version directly. This is already
done for some non-generated class registrations, e.g. in
`zend_enum_register_props()`.

Generated arginfo header files: combine preprocessor conditional blocks (#15736)

When functions' or class methods' availability is based on some preprocessor
condition, the generated arginfo header files wrap the declarations in the
preprocessor `#if` conditional blocks, one per declaration, even if they are in
the same conditional block based on comments in the stub file. Instead of
having multiple conditional blocks one after the other with the same condition,
combine them into a single conditional block.

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

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.

Support templated content

The template element in HTML 5 is special in the sense that it does not
add its contents into the DOM tree, but instead keeps them in a separate
shadow DOM document fragment. Interacting with the DOM tree cannot touch
the elements in the document fragment.

Make documentURI and URL not readonly (#13982)

These aren't actually readonly right now because `@readonly` means
nothing, and the setters are configured in php_dom.c. So no functional
changes here.

DOM spec marks these as readonly, but the problem is that this reduces
usefulness in XML contexts (like WSDL scheme handling). In context of a
browser, for which DOM was designed, this actually makes sense to have
as readonly because it is tied to the origin of the page etc. But PHP is
not a browser. This also wasn't readonly in "old DOM".

Strict error checking is always true for classes in "new DOM".
This means that we always throw an error when calling

actually possible.
Also change the stub to reflect this.
