PR description:

~/CMSSW_12_0_1/src/Validation/Geometry/test/MaterialBudget.py is updated;

• Syntax is upgraded from Python2 to Python3, this is necessary as per the migration to Python3 (MaterialBudget.py will not run without these changes).
• No dependency on any other PR's or externals.
• https://www.python.org/download/releases/3.0/

PR validation:

Tracker Material Budget Validation was run with CMSSW_12_0_1 (https://twiki.cern.ch/twiki/bin/viewauth/CMS/TrackerMaterialBudgetValidation - TWiki needs to be updated), "Validation plots: single geometry configuration" were produced (.png and .pdf files that illustrate the tracker material budget, measured in fractional radiation lengths x or hadronic interaction lengths l, plotted as a function of eta, or phi, or R, or eta and phi, etc.).

• "Validation plots: single geometry configuration" cannot be produced when MaterialBudget.py is run in Python2 syntax - upgrading to Python3 syntax is necessary.
• Relevant TWiki page (needs to be updated): https://twiki.cern.ch/twiki/bin/viewauth/CMS/TrackerMaterialBudgetValidation

@conetthuerta, I'd suggest to close this PR.
