When we write a cached test result, we now also write a log of the environment variables and files inspected by the test run, along with a hash of their content. Before reusing a cached test result, we recompute the hash of the content specified by the log, and only use the result if that content has not changed. This makes test caching behave correctly for tests that consult environment variables or stat or read files or directories. Fixes #22593.
