Title: refactor(NgElement): NgElement inject RootScope instead of Scope.

NgElement only uses scope to access rootScope, so now we directly inject
RootScope.

This is needed for future change #1429 which disallows Scope injection
into controllers. Since NgElement depends on scope it would also be
disallowed, unless we change it to directly use RootScope.
