Revert of Integrate registry_hash_store_contents with the rest of tracked prefs. (patchset #24 id:460001 of https://codereview.chromium.org/2204943002/ )

Reason for revert:
This CL is suspect of breaking WebRTC Windows bots.
I will reland if it doesn't fix the problem.

Revert of Integrate registry_hash_store_contents with the rest of tracked prefs.
(patchset #24 id:460001 of https://codereview.chromium.org/2204943002/ )

Reason for revert:
This CL is suspect of breaking WebRTC Windows bots.
I will reland if it doesn't fix the problem.

See, for example,
https://build.chromium.org/p/chromium.webrtc/builders/Win7%20Tester/builds/30...
