8.4, no backwards compatibility alias is needed.

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)

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.

Allow ZEND_ACC_VIRTUAL to be used to not have property backing storage without resorting to hooks

This is useful to reduce the memory usage of objects that don't actually
use the backing storage. Examples are XMLReader and DOM. When the
properties were added to the stubs, these objects became much much
bigger, which is a waste of memory.

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.

Remove ZEND_STATIC_ASSERT() calls from legacy arginfo files

gen_stub: Intern the parameter name string for named arguments in internal attributes (#14595)

This is necessary because `zend_get_attribute_object()` will use the persistent
string with the parameter name as the index for a newly created non-persistent
HashTable, which is not legal.

As parameter names are expected to be short-ish, reasonably common terms and
need to sit around in memory anyways, we might as well make them an interned
string, circumstepping the issue without needing to duplicate the parameter
name into a non-persistent string.

Improve BC support of arginfo files fenerated by gen_stub.php (#13705)

- Declared compatibility expectations of stub files are now enforced by a ZEND_STATIC_ASSERT call at the top of arginfo files
- Property registration for PHP 7 is fixed: function zend_declare_property_ex() is used again instead of zend_declare_typed_property(). This has been a regression since I added support for exposing doc comments.
- As a defensive measure, deep cloning is performed before newer features (type declarations, attributes etc.) are discarded before generating legacy arginfo files. Until now, some of the objects were forgotten to be taken care of. These omissions may have resulted in some weird bugs in theory (but probably they didn't have much impact in practice).
- PHP version related conditions inside *non-legacy arginfo files* used to possibly check for the 70000 version iD until now if compatibility with PHP 7.0 was declared in a stub. This was not 100% correct, since non-legacy arginfo files are only for PHP 8.0+. Now, I made sure that at least PHP version ID 80000 is used in the preprocessor conditions. The solution was a bit tricky though...
