feat: refactor pipelines into reusable workflows

This change refactors the build, test, and benchmarking pipelines to a
`presubmit` and `trunk` parent workflow which invokes other reusable
workflows. This simplifies the deluge of pipelines that are executed,
allowing for better orchestration and reduced noise on failures (only
one email will be sent instead of several).
