Schedule B-tagging on jets in GNNVertexFitterAlgCfg
As suggested by @dguest, the easiest solution for the time being to fix the GNNVertexFitterAlg is to avoid the BTagging object entirely. This MR configures GN2 to run directly on the jets, and then adjusts the GNNVertexFitterAlg to read the decorations from the jets rather than the BTagging object.
Also removes the selections on the vertices by default. Since these may be an analysis-specific choice, it makes more sense to apply any vertex-level selections downstream. The selection on maxChi2 is kept though to avoid very poorly fitted vertices.
