LibJS: Rename JS_ENUMERATE_{ERROR_SUBCLASSES => NATIVE_ERRORS}

Browse source 
The fact that they *are* subclasses is an implementation detail and
should not be highlighted. The spec calls these NativeErrors, so let's
use that.
Also added a comment explaining *why* they inherit from Error - I was
about to change that :^)
