Remove CI triggers (pushes to main/release/feature) from the public pipeline since those are already handled by the internal DevDiv pipeline. Add fork-only condition to all stages so non-fork PRs skip immediately, freeing up dnceng-public pool usage. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Pull request overview
Updates the public Azure DevOps pipeline configuration to avoid duplicating CI work already covered by the internal DevDiv pipeline, conserving public build pool capacity by ensuring the public pipeline only executes for fork-based PRs.
Changes:
- Disabled branch CI triggers in the public pipeline via
trigger: none. - Added fork-only stage conditions using
System.PullRequest.IsForkso stages skip for non-fork PR validations.

Description
The dnceng-public pipeline (
azure-pipelines-public.yaml) currently runs CIbuilds on pushes to
main,release/*, andfeature/*, and also triggers forall PRs (not just forks). This duplicates work already handled by the internal
DevDiv pipeline, wasting public pool resources.
This PR restricts the dnceng-public pipeline to only run for fork PRs:
trigger: noneso pushes to main/release/featureno longer trigger builds on dnceng-public.
eq(variables['System.PullRequest.IsFork'], 'True')so non-fork PRs thatstill trigger the pipeline will skip all stages immediately.
The
pr:trigger cannot filter by fork status in YAML, so non-fork PRs willstill trigger the pipeline, but no stages will execute.
