Investigate type hierarchy support for Bake targets

Bake targets can use the `inherits` attribute to inherit attributes from one target to another target. The LSP declares a couple of different requests that we should consider researching to understand the UX and whether this would benefit users.

LSP requests:
- `textDocument/prepareTypeHierarchy`
- `typeHierarchy/supertypes`
- `typeHierarchy/subtypes`
