Description Sam Weinig 2020-10-28 09:09:21 PDT

We have too many ways of overriding preferences in LayoutTests - test header commands, internals.settings, testRunner.overridePreference, and testRunner specific functions.

We should standardize on just test header commands for static configuration (as this is the only method that allows the preference to be set prior to a test run) and internals.settings as this is completely generated and allows dynamic setting of preferences.
