Adopt argsCanBeInterpretedByShell

[roblourens]

When a debug adapter uses RunInTerminalRequest, vscode is now escaping characters for the shell by default, but we added a flag to RunInTerminalRequest to allow debug adapters to disable this escaping, which some users want. A user pointe this out for java in microsoft/vscode#160999. This is adopted in js-debug and python, and I'd love to see it adopted for java. In js-debug and python, the args property can be a string or an array of strings. If it's just a string, the args are not escaped. I can talk more about what it will take to adopt this if needed.

@roblourens thanks to triage the issue to Java debugger side. I will take a look at this new capability.
