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.

Rename getStructFieldOffset/Type() parameter

By convention, parameter names of camel case methods should also
be camel case, i.e. the name should be $fieldName rather than
$field_name.

However, following GH-7236, which changed $arg_index to just $index,
this also changes $field_name to just $name. The fact that it is
a field name is obvious from context.

Rename FFI `getFuncArg*` to `getFuncParameter*`, $arg_index->$index (#7236)

PHP is already already using "Parameter" instead of "Argument" for reflection on types elsewhere.

Parameter is used to refer to the function declarations
(AST_PARAM internally in the AST, ReflectionFunctionAbstract->getParameters(),
etc.)
Argument is used to refer to expressions passed to the functions by the caller
(ArgumentCountError, etc.).
(Error messages were also changed in php 8.x to refer to passing too many arguments to a
function)

Other languages use similar definitions,
e.g. https://developer.mozilla.org/en-US/docs/Glossary/Parameter

Add support for union types for internal functions

This closes the last hole in the supported types for internal
function arginfo types. It's now possible to represent unions of
multiple classes. This is done by storing them as TypeA|TypeB and
PHP will then convert this into an appropriate union type list.

Closes GH-6581.
