Refactor tapeout for Chisel 3.4, Firrtl 1.4

- Remove clk package based on discussion with Colin
- Annotations need to be refactored to using latest API
  - Generally that involves making annos generated by a anonymous ChiselAnnotation
  - The chisel annotations will use RunFirrtlTransform to queue up its associated transform
  - Chisel annotation provieds toFirrtl to generate Firrtl form of annotation
- Usages of unapply on firrtl annotations cannot use generic unapply(target, transform, data) which has been eliminated
- Have transforms use with DependencyAPIMigration to avoid deprecated `form`s
- Added some 'see License comments
- TechnologyLocation section of AddIOPadsSpec does not currently run because there is no content for it.
  - Added some tests for annotation serialization here
