Update InDetGlobalMonitoringRun3Test to use TrackParticle + general cleaning

Thomas Streblerrequested to merge
tstreble/athena:TrackPart_IDGlobMonRun3 into master

With !54223 (merged) the computation of the expectInnermostPixelLayerHit and expectNextToInnermostPixelLayerHit Trk::TrackSummary variables will be moved into the xAOD::TrackParticle creation and won't be available in the original TrackSummary any more. This MR updates the InDetGlobalMonitoringRun3Test algorithms to use the xAOD::TrackParticle as base class to retrieve the summary fields, instead of the Trk::Track.

Similar to !54773 (merged)

For master alone to avoid disturbance in data-taking monitoring.
