Add PHP 8.1 Support

[gnat42]

This adds supports for PHP 8.1

[gnat42]

This is based on top of the PR for 8.0 rebased on top of the latest upstream master

The patch is incomplete and does not handle params by reference:

in ./zend/callable.h
the types' assignment code like:

case Type::String: info->type = (zend_type) ZEND_TYPE_INIT_CODE(IS_STRING, arg.allowNull(), 0);

should be:

case Type::String: info->type = (zend_type) ZEND_TYPE_INIT_CODE(IS_STRING, arg.allowNull(), _ZEND_ARG_INFO_FLAGS(arg.byReference(), 0, 0));

Nice catch. I've added the code (to more than just the string type parameter) I also found a php8.2 PR in a fork of this that also fixed another issue with my original php80 PR. Both of changes are in the original PHP8.0 PR since that's where it was changed and the original PR hasn't been merged.
