Settings WebUI: Enable a few more tests with Polymer 2.

Enabling the following tests:
 CrSettingsChromeCleanupPageTest.All (Removed usage of /deep/)
 CrSettingsMultidevicePageContainerTest.All (already passing)

Also fixing some overlapping inclusion and exclusion patterns (they
should not exist).
