Bug 1906827 part 3 - make cppunittests run on AArch64 r=ci-and-tooling,taskgraph-reviewers,jmaher,yjuglaret

Windows on AArch64 is a tier 1 target, and we'd like to run more (i.e.
some) tests there. I don't know if there's a plan to run everything on
AArch64, but this is an easy way to get some coverage, and as the bug
mentions some of these tests have been failing for a while on AArch64.
