feat(dart/transform) Remove import of dart:mirrors

+ Precede the call to `new ReflectionCapabilities()` with our generated
code which populates the reflection map statically.
+ Add the import of our generated code.
+ Once we are generating all necessary code, we will remove the
import of reflection_capabilities.dart and the instantiation of
`ReflectionCapabilities`, cutting the dependency on dart:mirrors.

Closes #761
