Port and optimise the full workflow from pixel raw data to pixel tracks and vertices to GPUs. Clean the pixel n-tuplets with the "fishbone" algorithm (only on GPUs). Other changes: - recover the Riemann fit updates lost during the merge with CMSSW 10.4.x; - speed up clustering and track fitting; - minor bug fix to avoid trivial regression with the optimized fit.

this PR (on top of #197) improves dramatically the speed of the Track Fit and of the clusterizer.
Physics results (besides numerics) are identical to #197 .
In my test the event throughput improves from 251.5 ev/s of #197 to ~326 e/s.
(I/0 limit at ~1KHz, GPU (GTX1060) 100% utilized)
