commands: remove debug package in commands

The package just causes the entire flow to be more complicated as build
has to pretend it doesn't know about debug options and the debugger has
to pretend it doesn't know about the build.

This abstraction has been difficult when integrating a DAP command into
this same workflow so I don't think this abstraction has much of a
value.
