Brett Lawson ad4e4c1aa8 ci: pin sccache-action's sccache version so jobs stop calling the REST API ...

Without a version input, mozilla-actions/sccache-action looks up sccache's
latest release through the REST API in every job that sets up the C++
reference (clippy, test and the four difftest jobs). Those calls spend the
repository's GITHUB_TOKEN quota, and once it runs out the step fails with
"API rate limit exceeded for installation", failing the job.

With a version the action downloads the release asset directly. v0.19.0 is
the release the latest lookup resolves to today, so CI behaviour is unchanged.
