VS Code VARIABLES View does not show DFDL Variables

{Sev: minor}

The VS Code view called VARIABLES does not show DFDL variables. This could be perceived as misleading when working with DFDL files.

Does the Daffodil internal debugger provide this information for external consumption?
If not, is there a way to remove the variables display area from VS Code?

Yes, the debugger has access to ParserOrUnparseState, which has a variableMapForDebugger member that contains information about all the variables (both current and previous instances). The CLI "info variables" debugger command has an example of how to access this state information:

https://github.com/apache/daffodil/blob/main/daffodil-runtime1/src/main/scala/org/apache/daffodil/runtime1/debugger/InteractiveDebugger.scala#L1939-L1989

Note that it only displays the current instance of each variable--an enhancement might be to give the ability to display all instances instead.
