Implement #78270: Support __vectorcall convention with FFI

To work around the limitation of the current rudimentary vectorcall
support in our patched libffi, we forbid yet unsupported declarations,
i.e. float/double parameters at certain positions (SIMD vector types
and HVA types are not supported anyway).

Fix bug #78752

NULL out the execute_data before destroying it, otherwise GC may
trigger while the execute_data is partially destroyed, resulting
in double-frees.

The handling of call stack unfreezing is a bit awkward because it's
a ZEND_API function, so we can't change the signature.

Fix bug #78226: Don't call __set() on uninitialized typed properties

Assigning to an uninitialized typed property will no longer trigger
a call to __set(). However, calls to __set() are still triggered if
the property is explicitly unset().

This gives us both the behavior people generally expect, and still
allows ORMs to do lazy initialization by unsetting properties.

For PHP 8, we should fine a way to forbid unsetting of declared
properties entirely, and provide a different way to achieve lazy
initialization.
