Record domains where Reader Mode is prompted or opened

Use RAPPOR to anonymously record the domains in two cases:
1. Reader Mode panel is prompted
   In AdaBoost heuristic, this means the page is distillable.
2. Reader Mode panel is opened by the user

There was an incident. The commit bot landed the original CL twice (388989c6665e2e46749eead442ffc942562d6e7b correctly, and then 8dd3c54659c4e99b4ba31254fed0094defd4ffd1 again, making the xml file malformed). I didn't noticed this until cherry-picking the CL to 2704 and found that only the xml file is modified.

I'll land a reversion of 8dd3c54659c4e99b4ba31254fed0094defd4ffd1 in master, revert c20fb9c0e07606b4667c60762cfcbcf9273602bb as well, and cherry-pick 388989c6665e2e46749eead442ffc942562d6e7b.

When cherry-picking 388989c6665e2e46749eead442ffc942562d6e7b, c20fb9c0e07606b4667c60762cfcbcf9273602bb is absorbed correctly, so no need to revert c20fb9c0e07606b4667c60762cfcbcf9273602bb on the branch.

Revert duplication of "Record domains where Reader Mode is prompted or opened"

This reverts commit 8dd3c54659c4e99b4ba31254fed0094defd4ffd1.

The commit bot wrongly landed https://codereview.chromium.org/1873073002/
twice, but only partially for the second time. This is fixed here.
