Rollup merge of rust-lang#70600 - danielframpton:aarch64-windows-tests, r=alexcrichton

Ensure there are versions of test code for aarch64 windows

Remove the `cfg` flags that were preventing some tests from running on `aarch64-pc-windows-msvc`.

All the existing `target_os = windows` targets had the same `align()` and `size()` values, so this change just removes the `target_arch` flags.
