x/build: add a Windows ARM builder

[toothrot]

Our current builder (generously contributed by @zx2c4) is ready to be turned down. We need additional hardware to keep supporting this platform, and can re-use the infrastructure from #42604.

We're running into a 0xc000007b failure when attempting to run arm32 binaries in our arm64 windows installation. It could be either the version of windows we have installed, or a strange interaction with QEMU and HVM.

Do we have any actual ARM hardware that we could copy the image to in order to determine whether the problem is with the WIndows version or the emulated host?
