Move existing BindGenerator test to its own directory and to test that
phase specificially, rather than the whole pipeline.
Add another BindGenerator test.
Use the parser in `BindGenerator`
This checkin also removes types from `registerSetters` calls since they
can cause runtime failures (see #886). We will resolve this by
generating change detector classes in the future.
Adds any metadata attached to a parameter to the "parameters" value
passed in to `registerType`.
For example:
`MyComponent(@Inject(Foo) foo)` generates
`"parameters": const [const [const Inject(Foo)]]`
Also reorganizes the testing code.
