CA extension to strips (14_2_X)

[bdanzi]

PR description:

This PR should introduce the usage of strips layers to the offline reco and HLT Cellular Automaton usage (same work done for 15_0_0_pre1):

• the strip addition and the changes in performance are expected only if using the customizer customizeHLTforAlpakaStrip for HLT and stripNTupletFit for offline reco, final geometry (Geometry/CommonTopologies/interface/SimplePixelStripTopology.py) pairs is still work in progress
• little gain in performance for the CA applied to pixel only due to the removal of minYsizeB1 and minYsizeB2 cuts + generalization of Kernel_simpleTripletCleaner
  Test on TTbar PU EOR3 TRK DPG v7:
  http://uaf-3.t2.ucsd.edu/~bdanzi/plots_pixelsOnlyValidation_AllCases/plots_hlt_hltPixel/effandfakePtEtaPhi.png where results in blue and red are produced with a cleaned 14_2_0 CMSSW release while the black one comes along with this PR changes

PR validation:

Before submitting I was checking

it's probably more practical to submit this upstream to cms-sw/cmssw already; can name this as "RFC" or a draft if some tests/updates are not completed.

The code base is ~ decoupled from mkfit.
