Issue describing the changes in this PR

Resolves #4420

I'm fixing the consolidated pipeline to automatically trigger when a build is done on either the core-tools.official pipeline or the core-tools-host pipeline. However we want to distinguish between nightly builds and regular builds that were triggered by CI. Therefore, we can separate the nightly build artifacts from the CI triggered artifacts by uploading the nightly build artifacts to an internal feed.

The format of the artifact version will be: YYYY.MMDD.buildId (where MM has no leading zeros).

Here is an example of the feed:
https://azfunc.visualstudio.com/internal/_artifacts/feed/core-tools-nightly-build

This PR also conditionally downloads the artifacts from the nightly build feed in the consolidated pipeline, if the consolidated pipeline run is also only a nightly build. Otherwise, we just take whatever was triggered by CI and use that build.

Note if the consolidated pipeline is manually run, we just use whatever is the latest run (regardless of nightly build or not).

The artifacts have also been updated to being with func when published, such as func-cli
