Instead of having clients directly register a callback with VS,
implement a Rust level callback interface in vmclient. This saves an
extra binder call on each notification, a bunch of boilerplate code,
and allows us to provide a slightly better interface (e.g. we can use
the Rust DeathReason enum, as elsewhere in vmclient, for instantly
better logging).
I also replaced all our usages of <some_interface>::binder::{...} with
direct access to binder::{...}. That makes it clearer what depends on
the interface itself and what is just generic binder code. I realise
this should be a separate change, but I only realised that after doing
bits of both.
Test: composd_cmd test-compile, observe logs (on both success & failure)
Test: atest -b (to make sure all our tests build)
Test: Presubmits

Now that we have wait_for_death_with_timeout, use it.
Test: Hack VM to not exit, see timeout error
