Unify extension behavior checks
Some supportsExtension and isExtensionEnabled checks are now turned
into checkCanUseExtension checks. Using checkCanUseExtension is
preferable so that warnings are generated correctly when an extension
is used and a warn directive is present.
isExtensionEnabled is still used in some places where an error message
about the extension could be confusing, particularly when a core spec
version adds support for something that is also present in an
extension.
Also make it possible to disable ARB_texture_rectangle extension using
an extension directive. ARB_texture_rectangle extension functionality
is enabled by default in GLSL when the extension is supported.
