perf(lsp): cancel ts requests on future drop (#21387)
When an old request is obsoleted while the user is typing, the client
will say so to the server and tower-lsp will drop the future associated
with that request.

This wires that up to the ts server by having any request's token be
cancelled when the surrounding state is dropped.
