This will fix:
#78821
and will probably speed up a bunch of other benchmarks.

If hot reload can change the information that is cached here, then we need a way to either disable this, or a way to invalidate the cache. There is already a cache with some entries which could be affected by this.

There's an issue #50978 to add a MetadataUpdateHandler for mono to clear reflection caches. (we also have caching in native that we need to clear, and that's not done yet, too). /cc @fanyang-mono
