Internally, a "component detection" task is automatically injected into builds to make sure we're not using any components with known security vulnerabilities. Because this task runs during the main app builds, it doesn't also need to run in the pipeline which hands off strings to the localization system.
* Move build jobs to the Hosted VS2017 pool instead of our internal pool
* Move the prepare-release-internalonly job from a team-specific pool to a shared pool with more capacity
* Remove symbol publishing from PR/CI builds since it's not necessary; do it only in release builds
