A few people have expressed that they'd prefer if the formatter did this rather than eslint. dprint can do this a lot faster without the linter errors; if you save on format it'll be extra good.

The downside is that we will lose automatic grouping, until maybe dprint/dprint-plugin-typescript#493. That's something I was relying on in #51455 to ensure the namespace imports always came first, but that could be achieved another way.

I also discovered dprint/dprint-plugin-typescript#620, but that's not a very bad bug.

I had to disable formatting in _namespaces, as those import orders matter and dprint does not have the ability to ignore regions: dprint/dprint-plugin-typescript#411
