Revert "Assign priorities to configuration scopes (#48420)" (#49185)

All the build jobs in pipelines are apparently relying on the bug that was fixed.

The issue was not caught in the PR because generation jobs were fine, and
there was nothing to rebuild.

Reverting to fix pipelines in a new PR.

This reverts commit 3ad99d75f9.
