Align telemetry workflow build with main CI pipeline

Match reusable-build-test-config.yml exactly:
- Use XRPLF/actions/prepare-runner for system-level ccache setup
- Use XRPLF/actions/get-nproc for dynamic parallelism
- Remove redundant Conan package cache (remote is the cache)
- Remove explicit CMake compiler launchers (prepare-runner handles it)
- Add CCACHE_SLOPPINESS and print-env step
- Pin action versions to commit SHAs
- Move secrets and github.event.inputs to env blocks
