Fixes dotnet#102259. Delegate creation requires form of lookups that are hard to express across inlined generics. This was introduced when we started doing more generic inlining in dotnet#99265. I [suspected](dotnet#99265 (comment)) things might not be correct here but assumed we'd have test coverage for sure. _Now_ we have test coverage.

Noticed this when working on dotnet#102299. This is bypassing the `CORINFO_LOOKUP_NOT_SUPPORTED` backout logic. Didn't actually test this, I'll let CI decide if this is a good change.

CoreCLR uses a slow fallback path for the complex delegates like the one used in the repro. The slow fallback path ( NativeAOT does not want to depend on full type loader to create delegates. You can think about it as NativeAOT-specific optimizations that is not implemented in CoreCLR (yet). |
