Bug 1925145 - Add updated Windows SDK and fix CaR builds. r=firefox-build-system-reviewers,glandium

The windows chromium-as-release (CaR) builds recently updated the
minimum windows SDK version required to complete the builds. This patch
adds this new sdk toolchain and also keeps it separate for just these
builds.
