kernel/svc: Provide implementations for svcDumpInfo/svcDumpInfoNew 

These are fairly trivial to implement, we can just do nothing. This also
provides a spot for us to potentially dump out any relevant info in the
future (e.g. for debugging purposes with homebrew, etc).

While we're at it, we can also correct the names of both of these
supervisor calls.
