Support BranchProbabilityInfo in update_analyze_test_checks.py (#72943)

- Change `BranchProbabilityPrinterPass` output to match expectations of `update_analyze_test_checks.py`.
- Add `Branch Probability Analysis` to list of supported analyses.
- Process `llvm/test/Analysis/BranchProbabilityInfo/basic.ll` with `update_analyze_test_checks.py` as proof of concept. Leaving the other tests unchanged to reduce the amount of churn.
