JIT baseline: trigger optimized compilation on hotness threshold.

- Add a new hotness count in the ProfilingInfo to not conflict with
interpreter hotness which may use it for OSR.
- Add a baseline flag in the OatQuickMethodHeader to identify baseline
compiled methods.
- Add a -Xusetieredjit flag to experiment and test.

Bug: 119800099
Test: test.py with Xusetieredjit to true
