Revert "Remove Windows debug bots from consoles"

This reverts commit 025bf217.

Reason for revert: Broke changes in //testing/buildbot. Will reland with a fix to that. Sheriffs should still not be alerted to failures on these bots in sheriff-o-matic even when this is reverted.

Original change's description:
> Remove Windows debug bots from consoles
> 
> They've been a bit flaky, and I don't want to bother sheriffs with them
> yet.
