Enabling warnings for NativeAOT reports some warnings. We should fix these.

Keeping a list of each of them individually, so they can also be fixed individually.

Ref: #18571.

  • ObjCRuntime/Blocks.cs(502,4): Trim analysis warning IL2075: ObjCRuntime.BlockLiteral.GetBlockForDelegate(MethodInfo, Object, UInt32, String): 'this' argument does not satisfy 'DynamicallyAccessedMemberTypes.NonPublicMethods' in call to 'System.Type.GetMethod(String, BindingFlags)'. The return value of method 'ObjCRuntime.BlockLiteral.GetDelegateProxyType(MethodInfo, UInt32, MethodInfo&)' does not have matching annotations. The source value must declare at least the same requirements as those declared on the target location it is assigned to.
