Only pass the method context when tracking transitions.

[jkoritzinsky]

Create a new helper instead of modifying an existing one. Only track transitions when we absolutely need to.

Fixes #47223

ReadyToRunInfo::GetEntryPoint should have something like this:

if (CORProfilerTrackTransitions() && pMD->HasUnmanagedCallersOnlyAttribute())
{
   pMD->SetProfilerRejectedPrecompiledCode();
   goto done;
}

Jit changes look fine.

Why is the last commit needed? These callouts should be limited to JIT only. We would have to introduce a whole new separate R2R image flavor to make that work. It is not something we want to do.

[jkoritzinsky]

I may have been a little overzealous on adding all the R2R helpers. I’ll go remove the e R2R helpers and just update the JIT helpers on the Crossgen2 side (which is all I really needed to do on that commit)

[jkoritzinsky]

Can you take a look at the 2 new commits and let me know what you think?

[jkotas]

LGTM otherwise.
