debugpy.breakpoint really shouldn't need debug mode

[bobrenjc93]

It's very unergonomic. The internal fork at my company allows for something like

import debugpy_fork; debugpy_fork.set_trace()

and it'll automatically start a session even if there was no debug mode active. Is there a way we can support this as well?
