bitbake-diffsigs: fix regression after recent server changes

We were bridging the gap between the server and UI here by calling a
bb.siggen.find_siginfo, a function defined and set on that module from
the metadata. This worked from the UI side before but since the recent
server changes is no longer accessible. Create a new command so this can
execute on the server side and return the result by way of a new event.

(We're still running compare_sigfiles() on the signature generator but
that isn't quite the same thing and does still work.)

Fixes [YOCTO #11844].
