[ci] Use drop service for SDK insertion artifacts (#9116)

Context: xamarin/yaml-templates@8759ec9
Context: xamarin/sdk-insertions#149

Steps to upload release artifacts to custom blob storage have been
replaced with azure-artifacts-drop (aka.ms/drop).

A new version of nuget-msi-convert has been added that will create a set
of artifact drops for the following shipping artifacts:
  * nugets
  * vs-components
  * vs-packs

The nugets drop contains all shipping packages that should be pushed to
various feeds or NuGet.org.

The components and packs drops are used for VS insertions.
