Previously zend_parse_parameters (and FastZPP) would handle invalid
arguments depending on strict_types: With strict_types=1, a TypeError
is thrown, with strict_types=0 a warning is thrown and (usually) NULL
is returned. Additionally, some functions (constructors always and
other methods sometimes) opt-it to throwing regardless of strict_types.
This commit changes zpp to always generate an Error exception in
PHP 8.
Even with some of the zpp variation tests removed in php#3783, this is
going to need a lot of test updates, as many tests are also testing
zpp failures. I haven't really started on this yet.
