perf(dart/transform) Restructure transform to independent phases

Update summary:
- Removes the need for resolution, gaining transform speed at the cost
  of some precision and ability to detect errors
- Generates type registrations in the package alongside their declarations
- Ensures that line numbers do not change in transformed user code

+Tests that the reflection removal step:
+ 1. Comments out the import of reflection_capabilities.dart
+ 2. Comments out the instantiation of `ReflectionCapabilities`
+ 3. Adds the appropriate import.
+ 4. Adds the call to `setupReflection`
+ 5. Does not change line numbers in the source.
+ 6. Makes minimal changes to source offsets.
