Port php c extension to php8 (#7793)

* Only ported c extension to php8.
* Didn't fixed the issue of throwing warnings for missing arginfo in bundled files.
* Tests not fixed, because syntax of phpunit (<7 vs >9.3) are not compatible.
* In next release, needs to drop php5 and php7.0 support (in order to use phpunit > 7)
