Add run number to vertex id for truth tracking

[jdkio]

Adds run numbers to vertex ids to track the true particle properly. That's required because run number indicates whether it's an anti-fiducial interaction or fiducial.

Also store "global vertex id", which is run_number * 1e6 + vertex id. That's a bit more stable than requiring that we carry around the pair, though it has its own downsides if vertex id > 1e6. Currently we don't expect it to.

This adds the missing information that's needed for the CAF maker, removing the need for the complex edep sim vertex location mapping. For more information, see this PR. Note that we don't want to revert the PR fully as it was fixing something more generally.

nice, solid fixes here.
Note that there is RunNo vs. ParticleRunNo/TrueVtxRunNo normalization asymmetry:

• RunNo vs. ParticleRunNo/TrueVtxRunNo/VertexGlobalID disagree on run-number normalization. TMS_TreeWriter.cpp adds:

static int normalizeRunNumber(int run) {
    return run >= 1000000000 ? run - 1000000000 : run;
}
...
RunNo = normalizeRunNumber(event.GetRunNumber());

This is the most likely thing to bite a CAFMaker user silently.
