Add ability for intrinsics to require GLSL extensions
When cross-compiling, we need to detect when an intrinsic is used that required non-default GLSL capabilities and emit an appropriate `#extension ... : require` line.
I'm handling this by attaching a custom modifier to declarations that require an extension in order to be callable.
