[llvm-mca] Move the logic that prints register file statistics to its own view. NFCI
Before this patch, the "BackendStatistics" view was responsible for printing the
register file usage (as well as many other statistics).
Now users can enable register file usage statistics using the command line flag
`-register-file-stats`. By default, the tool doesn't print register file
statistics.
