Pixel Tracks (DIGI-RECO) for Phase2 for 11_1_X

[AdrianoDee]

Allowing to run Pixel Tracks from Digis Clustering to Pixel Tracks (GPU/CPU). Placing it here to have it clean somewhere and get suggestions, corrections, comments. Not intended to be merged (I think) especially before integration.

• Moving phase1PixelTopology to pixelTopology to include Phase2 topology
• Given that sizes, n_cols & n_rows varies from det to det, added nRowsRoc nColsRoc nRows nCols numPixsInModule to DetParams
• Modules, histograms, max constants moved to accomodate D49 Geometry (3892 modules in 28 layers) and PU200 (nHits->180k nQuads->30k nTrips->200k, would probably need to increase maxTuples up to 512k)
• Adding SiPixelClusterDigisCUDA producer for building Clusters direclty from Digis
• Adding kernels for Phase2 Digis in SiPixelRawToClusterGPUKernel.h: calibDigisUpgrade comes from PixelThresholdClusterizer (here) with params from here and here
• Extended PixelCPEFast for Phase2 pixels/geometry. CPE with errors from size (no DB yet).
• RiemannFit & BrokenLine fit to use as input tuples with up to 16 hits (4 + 12)
• Adding Upgrade flag all around

Will continue adding material here (included plots & timings).

TODOs/TOADDs (?):

• [ ] "forward"-port to 11_2_X, realigning with commits from integration
• [ ] add config to run this and proc modifiers
• [ ] some debugging stuff cleanup
• [ ] add DENSE_EVENTS to gpuClusteringConstants
• [ ] make ElectronPerADCGain & co. configurable
• [ ] extend BrokenLine & Riemann to fit nHits
• [ ] upload a bunch of plots for detailing cuts & validation

ok. let's test this for Run2/Run3
