This adds a pretty printer for firrtl.annotation.Target and associated
tests. This uses a tree-like output where the following target
~Circuit|Module/foo:Foo>ref.field[0] will serialize to:
circuit Circuit:
└── module Module:
└── foo of Foo:
└── ref.field[0]
This enables better error messages and a human readable syntax better than
the existing serialize method (and avoiding the need for users to
understand the Target serialization syntax), but that is not intended to
be deserialized nor space efficient.

Formerly #865
Major Code Changes/Features Added:
Added Target trait as replacement for Named
Added TargetToken as token in building Target
Added GenericTarget as a catch-all Target
Added CircuitTarget, ModuleTarget, ReferenceTarget, and InstanceTarget
Added ResolvePaths annotation
Added EliminateTargetPaths (and helper class DuplicationHelper)
Updated Dedup to work with instance annotations
Updated RenameMap to work with instance annotations
DCE & ConstantProp extend ResolveAnnotationPaths

This reverts commit 7e2f787e125227dc389d5cf1d09717748ecfed2e.

Added Target, which now supports Instance Annotations. See #865 for details.

- Old Annotation renamed to deprecated LegacyAnnotation
- Annotation is now a trait that can be extended
- New JsonProtocol for Annotation [de]serialization
- Replace AnnotationMap with AnnotationSeq
- Deprecate Transform.getMyAnnotations
- Update Transforms
- Turn on deprecation warnings
- Remove deprecated Driver.compile
- Make AnnotationTests abstract with Legacy and Json subclasses
- Add functionality to convert LegacyAnnotations of built-in annos
This will give a noisy warning and is more of a best effort than a
robust solution.
Fixes #475 Closes #609

Also add GlobalCircuitAnnotation for creating similar annotations
