Enable the latest managed pgo data (#49793)

- Implementation is parallel to existing ibc handling, so that it can be toggled on/off by adjusting the `UsingToolIbcOptimization` property
- Use the same data for all assemblies produced in current build
- Apply data to release builds only
- Disable mismatch assertions in jit for current state where il mismatches are common
