[BinFmt] Usage of BinaryFormatter in tests

[rokonec]

During migrating to new arcade using dotnet8 we have encounter few errors related to usage of deprecated BinaryFormatter,

It seems we are using BinFmt in some tests:

• AssemblyNameEx_Tests - we probably do no longer need binaryformatting of AssemblyNameEx

• msbuild/src/Framework.UnitTests/EventArgs_Tests.cs

  Lines 56 to 68 in a9034a2

  	/// <summary>
  	/// Verify a whidbey project started event can be deserialized, the whidbey event is stored in a serialized base64 string.
  	/// </summary>
  	[Fact]
  	public void TestDeserialization()
  	{
  	string base64OldProjectStarted = "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";
  	BinaryFormatter bf = new BinaryFormatter();
  	MemoryStream ms = new MemoryStream();
  	byte[] binaryObject = Convert.FromBase64String(base64OldProjectStarted);
  	ms.Write(binaryObject, 0, binaryObject.Length);
  	ms.Position = 0;
  	ProjectStartedEventArgs pse = (ProjectStartedEventArgs)bf.Deserialize(ms);

  
  whidbey seems to be VS2005 - I don't think we need it anymore, if VS still uses it they shall fix it soon - we don't need test for it

• msbuild/src/Framework.UnitTests/LoggerException_Tests.cs

  Lines 49 to 57 in a9034a2

  	public void SerializeDeserialize2()
  	{
  	LoggerException e = new LoggerException("message");
  	using (MemoryStream memstr = new MemoryStream())
  	{
  	BinaryFormatter frm = new BinaryFormatter();
  	frm.Serialize(memstr, e);

  
  I thing this has been addressed in recent Jan changes in SerializationContractInitializer and we do no longer need to BinFmt LoggerException and whole LoggerExceptionTests class can be deleted

NOTE: @JanKrivanek FYI
