Add Microsoft.MSBuildCache (#17393)

Add Microsoft.MSBuildCache

This change adds a new pipeline which enables caching in the build. This
is added as a separate pipeline for now with the eventual goal of
enabling for PR and/or CI builds.

Documentation for Microsoft.MSBuildCache can be found in the GitHub
repo: https://github.com/microsoft/MSBuildCache
