Move variable typed ops to NamedArray

[headtr1ck]

• xref NamedArray tracking issue #8238

This is highly WIP and probably everything is broken right now...
Just creating this now, so other people don't work on the same :)
Feel free to continue here with me.

@pydata/xarray

1. what do we do with commonly used functions, is it ok to copy them?
2. Moving the typed ops requires a lot of functions to be added to NamedArray, is there a consensus of what we want to move? Is it basically everything?
3. Slowly the utils module is becomming a graveyard of stuff we dont want to put elsewhere, maybe we should at least move the typing stuff over to a types module.

I suggest moving them over and have Xarray depend on NamedArray, at least while we do the refactor.

Yes, I don't think there's much room to compromise on unary and binary ops.

maybe we should at least move the typing stuff over to a types module.
