internal/lsp/cache: refresh imports cache in the background

Now that we can detach scans, it's easy to kick off a background refresh
that doesn't block the user. Performance may be a bit worse until the
scan finishes, but that's the price we pay for freshness.

Adaptively rate-limit the refresh rate so that we don't turn the user's
computer into a hot plate.
