Remove metrics collector service trampoline
No longer needed to trampoline between RTTI and non-RTTI compiles.
Move the service impl from libmetricscollector service to the
metrics_collector executable, now that RTTI is no longer used (and the impl
is not used by binder clients).
Other fixups, including:
* Move service registration and binder watcher to metrics_collector main.
* Compile libmetricscollectorservice with clang just because.
