feat(php): Add PHP 8.5 support

[ptondereau]

Description

Fix #591

TODO

• Wait for the official Docker image to release PHP 8.5 images for MUSL CI.
• Test embed codes don't work with 8.5 right now.
• Windows tests are failing because of intsafe import in zend_compatibility, we need to find a way to tell clang to define them somewhere
