Add @ember/-debug-basic for internal use

[wagenet]

captureRenderTree requires @ember/-internals/glimmer which has a lot of dependencies. The rest of the root @ember/debug import is pretty isolated, so making @ember/debug/-basic for internal use reduces a lot of entanglement.

For #20303.

The prod build tests are legitimately failing because of changes from this PR, @wagenet – it looks like it's not even hitting all the expected assertions in most of the tests it's failing on.

Is this still relevant?

[wagenet]

I think so, but I haven't had the time to do anything and it's not urgent.
