…been removed There used to be a cli flag --experimental_multi_threaded_digest which defaulted to true and therefore would not compute the file digest in exclusive mode unless overridden to false. When that flag was removed this code was accidentally left behind which instead causes bazel to always compute file digests in exclusive mode for all files larger than MULTI_THREADED_DIGEST_MAX_FILE_SIZE. This causes bazel to take 5-6x longer to 'check cached actions' in my org's builds, specifically increasing the time from 30 secs to 2 mins 30 secs for fully cached no-op builds. Fixes bazelbuild#14034

There used to be a cli flag --experimental_multi_threaded_digest which defaulted to true
and therefore would not compute the file digest in exclusive mode unless overridden to false.
When that flag was removed this code was accidentally left behind which instead causes bazel to always
compute file digests in exclusive mode for all files larger than MULTI_THREADED_DIGEST_MAX_FILE_SIZE.
This causes bazel to take 5-6x longer to 'check cached actions' in my org's builds,
specifically increasing the time from 30 secs to 2 mins 30 secs for fully cached no-op builds.
