Add LSP kinds to "import" code actions

[isovector]

The current "import" code actions are pretty overwhelming, especially for commonly used names. We get the cartesian product of matches x styles.

I'd like to suggest we export import Foo.Blah under the kind quickfix.import.module and import Foo.Blah (what) under quickfix.import.definition. Users can then opt-in to their preferred style, and users/clients who don't care will still see today's behavior.
