Fix mixed -E and -e emission

Signed-off-by: Schuyler Eldridge <schuyler.eldridge@ibm.com>

Fixes a bug where an Emitter was only checking for the presence of an
EmitCircuitAnnotation or EmitAllModulesAnnotation to control its
emission flavor (one-file-per-module or one-file). This changes the
check to ensure that the class of emitter matches that of the
annotation. This allows for correct behavior when mixing different
emitters, e.g., -E high -e middle.

* Eliminate warnings on `sbt doc` and `sbt unidoc`
- removed toFirrtl reference on MultiTargetAnnotation
- lots of places where package path has to be added to comment references
- Change to use `/** text starts here` convention when wrong in comment with a doc fix.
  - Did not exhaustively change these
- Wrestled doc example in RenderDiGraph#renderNode, not sure if I won
- Cleaned up InferWidths & CatchExceptions imports
- Added missing license message to a couple of files.
- fixed a couple of stale parameter names in scaladoc
- Added @unchecked to stop erasure warning in Emitting where emission annotations are collected
- Change types to [_] on match in RenameMap#recordAll to fix erasure warning

* Where  possible change [[firrtl.ir.X]] to [[firrtl.ir.X X]] for better display in scaladoc

* Link to Java API Documentation

This adds a build.sbt apiMappings to allow for Scaladoc/Unidoc linking
to Java API documentation. This uses the exact strategy that Scala
upstream uses for linking.
