Add dedicated workflow for 'all' instrumentation meta-package

- Created ci-instrumentation-all.yml to handle the 'all' instrumentation
- This workflow triggers on any instrumentation/** or helpers/** changes
- Removed 'all' from ci-instrumentation.yml to avoid duplication
- Ensures 'all' instrumentation tests run for any instrumentation change
  as required for merging while maintaining CI optimization benefits
