Add annotations
@pragma('dart2js:load-priority:normal')
@pragma('dart2js:load-priority:high')
The test shows that these annotations are scoped.
This CL is just plumbing the annotation through as an argument to the runtime call to the code that implements `loadLibrary()`. Actual prioritization is not yet implemented.
