[skip ci] Remove PECL build

This build is not useful for multiple reasons:

- Legitimate API changes keep making the build red. Frequently it takes 3rd
  party extension developers months to fix these issues.
- Once we're annoyed enough by the red build we skip it and then don't revert it
  way after it has been fixed.
- True accidental API changes are incredibly rare. I don't believe I've
  experienced one yet.
- This build only runs for master, which is also the branch where accidental
  changes are least problematic.

Closes GH-21980
