CI: skip the workflows a push's samples and workflow files do not touch

Every push ran every workflow. tools/ci_paths.py now writes each
workflow's push and pull_request paths filter: everything, less the
samples trees and the other workflow files, plus the sample
directories its jobs build or run (through the scripts they call and
the paths those directories name in turn) and the workflow itself. A
push to one sample runs the full-tree builds no longer, only the
workflows that run that sample; a push to one workflow runs it alone;
any other change runs everything as before. Jobs that call a tool or
CI script, walk the samples trees or read the workflow files keep
those whole, and workflows with a filter of their own keep it.

The CI local runner workflow runs tools/ci_paths.py --check, which
fails when a filter no longer matches what its workflow names, and
tools/ci_local.py which reads past a generated filter to the coverage.
