Refactor game-related frame rate override to LayerHistory
Previously game-related frame rate overrides are maintained in Scheduler
only, which does not provide votes to the actual display refresh rate.
This causes an issue that these overrides will only be viable when they
are the divisors of the display refresh rate at the moment.
This change moves the game intervention and newly-added game default
frame rate overrides to LayerHistory, where overrides will be considered
in layer frame rate votes. Scheduler will get this information and
select the display frame rate accordingly
