Mac: Fix renderer idle cpu usage regression.
Since polling is required only for the preferred height and mac only needs preferred width, add a flag that specifies if the client is interested in width and/or height.
This is a band-aid, the Real Fix is tracked in 44850.
BUG=44494
TEST=Open chrome's task manager. Idle renderer processes should take close to 0 %cpu instead of ~1.5 before.
