Assembly.ReflectionOnlyLoad(...) is obsoleted, consider remove the unused reference in mono

[buyaa-n]

As part of #50529 we have obsoleted several APIs not supported in .Net Core which caused a build warning in mono CoreClr

I see the API calling Assembly.ReflectionOnlyLoad(...) is always called with a value of false for bool reflectionOnly parameter, which means that reference will never actually used. We might want to remove this parameter and related code section from

runtime/src/mono/System.Private.CoreLib/src/System/RuntimeTypeHandle.cs

Lines 290 to 291 in 90f97ac

	internal static RuntimeType? GetTypeByName(string typeName, bool throwOnError, bool ignoreCase, bool reflectionOnly, ref StackCrawlMark stackMark,
	bool loadTypeFromPartialName)

Not sure what the best approach is for associated tests - completely remove from test suite or disable for certain runs.
