- include all shipping packages in Helix payloads that need runtime
- remove hard-coded `-ci` that broke Helix tests with stable versions or local builds
- for local builds, do not assume `$(Configuration)` is Release
- support `$(HelixTargetQueues)` property used in RunHelix.ps1
- lost somewhere along the lines; script ran full matrix
nits:
- clean up redundant addition of runtime and ref/ packages
- `@(HelixContent)` additions in `_CreateHelixWorkItem` target are ignored
- mention '+' separation of `-HelixQueues` argument to RunHelix.ps1
- allow `$(IsUnitTestProject)` override in case we need it in the future
