Support it as a fallback target in detect-targets, and provide a release build for it

For arm64ec there's a rust target https://doc.rust-lang.org/nightly/rustc/platform-support/arm64ec-pc-windows-msvc.html

For arm64x I have no idea how to build it from cmdline, the official doc only shows how to do it in vs

cc @passcod for arm64x do you know how to build it?
