A test variant for a package can only be reloaded by running go/packages
on the non-test variants import path with the -test flag. We need to
cache this import path in order to be able to reload a test package
on-demand.
Also, always ignore test main packages by detecting them in the

- Kick off diagnostics in a goroutine to match how DidChange works.
This will allow us to work through big sets of file changes faster,
and will save duplicated work once type checking can be canceled.
- Don't assume a watched file is only part of one view.
Two interesting cases we don't handle yet:
- If the deleted file was the only file in the package, we don't
currently update diagnostics for dependent packages. This requires
rejiggering how diagnostics are invoked a bit.
- If the deleted file is still open in the editor and then later
closed, we don't trigger metadata/diagnostics refresh on DidClose.
