Context: #15761

Updates the build to use the latest MSI generation template. The v3
template uses the latest changes from arcade which include a large
refactoring, support for multi-targeting, and support for workload pack
group MSIs.

The build will now produce two different VS Drop artifacts. The MSI and
VSMAN files generated for SDK packs have been split out into a new
vsdrop-multitarget-signed artifact, allowing us to include multiple
versions of the SDK packs in VS.
