internal/lsp/source: support inverse "implementations"

Now "implementations" supports finding interfaces implemented by the
specified concrete type. This is the inverse of what "implementations"
normally does. There isn't currently a better place in LSP to put this
functionality. The reverse lookup isn't an important feature for most
languages because types often must explicitly declare what interfaces
they implement.

An argument can be made that this functionality fits better into find-
references, but it is still a stretch. Plus, that would require
find-references to search all packages instead of just transitive
dependents.

Updates golang/go#35550.
