Allow choosing EAGL or CGL at runtime
Dean Jackson made this change downstream in WebKit:
https://bugs.webkit.org/show_bug.cgi?id=216722
Change ANGLE to dynamically load either EAGL (OpenGLES) or CGL (OpenGL)
depending on both compile and runtime configurations.
Intel Mac -> CGL
Intel Mac Catalyst -> CGL
Intel iOS Simulator -> EAGL
iOS Device -> EAGL
Apple Silicon Mac -> CGL
Apple Silicon Mac Catalyst (with Mac app) -> CGL
Apple Silicon Mac Catalyst (with iOS app) -> EAGL
The trickiest bit is Apple Silicon Mac Catalyst, which depends on the
type of the application it is attempting to run. In that case ANGLE must
compile both the CGL and EAGL interfaces and then pick one to use after
launch.
