[wasm] [debugger] Evaluation of methods on enums

[ilonatommy]

Fixes #69299.

• Adding tests for calling methods on enums.
• Fixing evaluation of ToString overload with parameters and potentially other functions that might have empty-named parameter handles in method signature.

Original error:

System.IndexOutOfRangeException: Index was outside the bounds of the array

Reason:
parameter handle array and methodSignature.ParameterTypes array were not in sync, handle array had 3 elements, one of them invalid (with empty name) while method signature types had 2 elements. When we ignore invalid handles, the logic works fine. https://learn.microsoft.com/en-us/dotnet/api/system.enum.tostring

Out of scope:

• passing objects as method arguments. "mc.valueTypeEnum.HasFlag(SampleEnum.no)" is not evaluated correctly because we do not have the mechanism for object-params. Delegated to issue [wasm] [debugger] Evaluation of methods with object-param #92262
