Support for SxS workload manifests

[marcpopMSFT]

This is the initial work in arcade and the resolver to support SxS workload manifests
dotnet/designs#294

Arcade

• Change workload manifests to be SxS (currently they upgrade)
• Change workload manifests to install in a specific version folder

Workload resolver (overlap with workload set version)

• Look under the new path
• Read the workload set version
• Read the rollback file version when installed from rollback - Use install state in workload manifest provider #33643
• Support for global.json workload set version (sync with runtime on maybe adding built in support)
  • sync on serialization effort within global.json code
  • Error if trying to pin to a baseline workload set version (as those packs likely aren't available)
• TBD do we resolve the latest manifests available or the latest with packs installed <-- yes for now
• Make sure we don't explode if we both new and old install locations for manifests

Workload CLI

• Enable SxS workload manifest support for file-based installs #34032
  • file based install of SxS manifests
  • garbage collection for file based
• msi-based garbage collection
• Baseline manifest SxS support in installer repo for file-based installs #34280

Miscellaneous

• Engage Tizen on the planned changes to workloads and how it will work for their workload
