Raylib Php Versions Save

Fixes to LoadModel and LoadModelAnimations for better 3D support.

• LoadModel has correct sub-object mapping, but still missing material->materialmap->* sub object to still support https://github.com/joseph-montanez/raylib-php/blob/master/raylib.c#L8561
• LoadModelAnimations is mostly complete, crashing when its unloaded & garbage collected

Large rewrite of internals. Reduced memory usage and faster performance due to fewer op calls.

• PHP 8.2 support

• Added Matrix
• Fixed Camera2D copy issue
• Added Screen-space-related functions

• Initial PHP 8 Support, Upgrade to RayLib 3.5
• Camera2D improvements to API use i.e $camera->target->x++ is now possible without having to use getters and setters.

• Font loading

• Completed Window API
• Added more draw functions (triangle, fan, strip)
• Started adding read/write of properties rather than using getters and setters. This means no more $vec->setX($vec->getX() + 10), you can now use $vec->x += 10

• Added Wave functions
• Added more Texture calls
• Added draw Triangle calls
• Fixed some stubs for auto complete
