To workaround b/141025174, adding support for devices without display idle signals. Also added a property to override idle display function. Besides the idle signal support, this CL also makes touch boost duration tunable through several new vendor properties. It also named display idle monitor thread and cleans out the obsolete HIDL Power HAL implementation. Bug: 168080943 Bug: 169065024 Bug: 171494137 Test: Boot and trace Change-Id: I76067d10958654d539624ec4cac8f346103e67bc
