Erik Rose b1265899bc Bug 1681985 - Add and call Fathom ruleset. r=zbraniecki
* We make some changes to heuristicsRegexp.js to improve accuracy. (Nothing else uses these regexps, so they're safe to change.) The commenting out of some languages in the expiration fields are because they caused a lot of false positives, according to Daniel Hertenstein's recollection. In any case, we've never preffed CC autofill on for those languages.
* Delete a few tests from test_known_strings.js and one from test_getInfo.js, which were testing for the presence of regexes we removed.
* Delete tests of CC autofill against third-party sites. These tests no longer work as xpcshell tests, since Fathom expects full layout and style information. The spirit of these tests is maintained by adding these pages to Fathom's training, validation, and testing corpora at 2bfcdf23dc. A few don't make it due to iframes which confound Fathom's capture tools, but the rest all succeed--and now improve the ML model as well as acting as tests. The training results after said integration reflect this improvement, which boosts testing precision and recall for every type.
* Add a mochitest to ensure the Fathom integration code can surface a decision that a field should not be autofilled. Decisions that go the other way are taken care of by the existing autofill tests.
