JIT: block some struct promotion for OSR

[AndyAyersMS]

This undoes part of #65903. OSR methods can't rely solely on their own analysis
for struct promotion as they only see parts of methods.

This has a handful of diffs in the aspnet collection. It will also likely have a negative perf impact on microbenchmarks, but I won't know the magnitude of that until after merging and letting the lab get a few days' worth of data.

Unlikely that the libraries pgo will run cleanly, so I'll have to parse the results.

Not sure why SPMI is failing, looks like infrastructure perhaps?

Libraries failure is #66571

[AndyAyersMS]

Libraries PGO tests look to be improved overall.

SPMI seems to have passed on rerun but gotten a little confused.
