CI: Sync the Build Workflow from nuttx repo

[lupyuen]

Summary

This PR syncs the CI Build Workflow build.yml from nuttx repo to nuttx-apps. The updated build.yml consolidates these changes:

• CI: Improvement to speed up compilation and reduce download errors. nuttx#13301
• build.yml: Check out the correct branch of nuttx-apps nuttx#13806
• CI: Apply the Refactored Build Rules based on Arch Labels nuttx#13862

build.yml from nuttx repo was slightly modified for nuttx-apps:

• All References to apache/nuttx/.../arch.yml were changed to apache/nuttx-apps/.../arch.yml (we decouple them so they are easier to update)
• Removed pull_request > paths-ignore and push > paths-ignore (following the existing convention)

Impact

With the updated build.yml, nuttx-apps will be built according to the PR Arch Labels, as explained here: apache/nuttx#13775

This has no impact on nuttx-apps, since Arch Labels are not used in this repo. CI Build Workflow shall run the exact same way as before.

Testing

We verified that CI Build Workflow runs the exact same way as before.

With the updated build.yml, CI Build Workflow successfully recompiles examples/hello when we Submit a PR: https://github.com/lupyuen5/label-nuttx-apps/actions/runs/11229943812
