Apply strict_types to internal functions

Hello. I’m Saki Takamachi. Inspired by the issue below, I'm thinking of proposing this RFC. https://github.com/php/php-src/issues/12055 As the documentation below states, PHP's internal functions currently ignore strict_types. https://www.php.net/manual/en/language.types.declarations.php#language.types.declarations.strict I think the current spec is not intuitive, so I propose changing the behavior of the macro ZEND_ARG_USES_STRICT_TYPES() to allow internal functions to accept strict_types. I plan to make changes in zend_compile.h and zend_compile.c and do the changes myself, I haven't written any tests yet, but I'm thinking about making changes like this. https://github.com/SakiTakamachi/php-src/pull/1 As per How To Create an RFC, I will first try to gauge response to this proposal on the mailing list. Thank you Saki Takamachi
