The ILLink analyzer was not producing warnings for annotated methods, lambdas, or local functions accessed for delegate creation.

Some ExpectedWarnings for ILLink/NativeAot were updated to avoid relying on the name of the compiler-generated methods for lambdas or local functions, because the analyzer reports the warnings as:

IL2111: Method 'lambda expression' with parameters... is accessed via reflection.

Fixes #84918
