Test arm64 Github Actions runners

[marcustyphoon]

Apparently Microsoft now has Arm Neoverse N2 runners publicly available. Was curious if they worked without any code changes.

Edit: Nope, not yet, though it looks like there are relevant tracking issues in the image repos.

Nice, the ARM runner actually is faster. I guess Microsoft wasn't blowing hot air.

(Probably within margin of error, realistically, since I only did one test here, but close enough to par that ARM wins given an efficiency win, which I have to assume is real if Microsoft charges less for ARM runners when they aren't free.)

Seems to hold up decently, with some variation. And there should be improvements in the future like properly installing node out of the tool cache.

But this is not ideal:

Edit: Never mind, that's almost certainly because I manually cache the rust output without including OS/architecture in the cache key. My bad.
