With -mod=readonly (https://golang.org/cl/268597), changes to go.sum files will affect the results of packages.Load. We should handle changes to go.sum files in (*snapshot).clone and invalidate metadata in the same way that we do for go.mod files.

I don't think the description is quite correct. Specifically, a change to go.sum can take a broken packages.Load and fix it; if the load succeeded, then go.sum changes cannot be relevant. (Technically, they could break it, but I don't think we care about that.) So it's less that we should invalidate, and more that we should try again to fix any invalid metadata.

gopls/internal/regtest: test that accepting fix removes diagnostics

This test currently fails, as we don't treat go.sum updates as
invalidation events.

Updates golang/go#42815
