Subject: [PATCH 1/2] Build windows app package on PR

Use for now a static rootfs, do not do any other change, and pull
everything to latest.
This ensures we can always build before merging our windows app package
and attach it to the PR to sideload, without any further change.

Subject: [PATCH 2/2] Strip ARM64 from CI build solution.

We only want a testbuild on x64 and providing AppxBundlePlatforms="x64"
is not enough.
