Add Testing Integration Support to TDML

[michael-hoke]

Investigate integrating TDML Test Cases into VSCode's native Testing Integration tab.

• Get Test Cases to show up in the Testing Integration Window on the left hand side of VSCode.

• Figure out what duplicates look like in that window. Currently, test case name and description are used to detect duplicates. Add duplicate checking for test cases in a TDML file. This should, at a minimum, flag problems in the diagnostic window when duplicates exist. Duplicates are when the Test Case name and description match. XPath?

  • If it's possible to implement that as a part of the Append command that feels good for users, do it there as well.

• Remove the Execute command from DFDL's command palette

• Ensure that a test case can be executed from the Testing Integration Window

• Is there a way to easily edit the name/description of a test case? Possibly from the Testing Integration Window... Ideally, we want a way to allow the user to easily modify the name/description of an auto-generated test case
