Add test matrix for V3

[maxrjones]

Part of #1648

The extras are packages that should be optional (with import skipping), which could be addressed separately.

The current setup includes 8 combinations (below), would appreciate feedback on this.

$ hatch env show --ascii

@jhamman I think this is ready for review if you have time. Mypy predictably fails (#1593), so let me know if you think we should comment that step out in the CI for now.

[jhamman]

Looks great @maxrjones. A few suggestions but this is close to going in.

It would be nice if we could use github action's matrix feature here as well. Obviously, we're skipping lots of tests at the moment so running the whole matrix in one action is fine. But as the test suite comes back to life, I think we'll spread out. It seems like Hatch can support this with something like:

hatch run +py=${{ matrix.python-version }} test:run

Note: I wasn't able to figure out how to run individual matrix members with hatch variable selection but it seems like it should be possible: https://hatch.pypa.io/1.9/cli/reference/#hatch-env-run

I'm going to merge this now since I think its a solid improvement.

@maxrjones - if you come back to #1648, we can look into splitting the matrix runs out into a GHA matrix.

Thanks @jhamman! I'll be offline Feb 14 - March 5 and doubt that I will have time to work on this more before then. But, I'll be glad to contribute more after returning if there are still open V3 refactor issues.
