Preserve necessary type and method

[fanyang-mono]

Fixes #50721
For test System.Text.Json.Serialization.Tests.CollectionTests.WriteHashSetTOfHashSetT,
the line of code which triggered System.NullReferenceException was https://github.com/xunit/assert.xunit/blob/3e9f13f2fae7ff8f379da0f19f72d56aea2dae46/Sdk/AssertEqualityComparer.cs#L249
Thus, CompareTypedSets was the missing method. It is a method of type Xunit.Sdk.AssertEqualityComparer, which belongs to assembly xunit.assert.dll

Fixes #50717
Rewrite the way of getting the type System.Runtime.InteropServices.IDispatchImplAttribute.

Fixes #53647
Fix for #50721 also fixed this.

Fixes #51911
Simply enable the tests. Not reproducible anymore.

Could you add the reasoning for these changes, like what depends on it, and how/what fails?

    private const string TypeName = "System.Runtime.InteropServices.IDispatchImplAttribute";

Is TypeName still used?

Is TypeName still used?

Might be worth inlining ValueName as well. It feels like something that fell victim to "introduce a constant for the sake of introducing a constant". It's detrimental to readability.

@eerhardt and @MichalStrehovsky Are the changes looks okay with you?

[fanyang-mono]

All tests have passed actually. Ready to be merged.

Oops, I didn't notice that there were more than one test methods associated with that issue. Will Open another PR to enable it. Thanks for your reminder.
