Change debug adapter registration to pass /debugAdapter parameter

[daviwil]

VS Code debug adapter configurations have now been updated to accept an args array:

microsoft/vscode#1199

This can be used to replace the current .cmd file hack we use to pass the /debugAdapter parameter to the PowerShell Editor Services host process.

That will be a nice change for those of us debugging the debugger. :-)

[daviwil]

Yeah! We'll be able to throw /waitForDebugger in there now too :)

[daviwil]

Woohoo! They fixed it. Adding /waitForDebugger is very easy now so that we don't have to go to so much trouble to debug the debugger ;)
