Use HeapGrowthMultiplier for native allocaitons
Reduces the amount of native allocation GCs for foreground apps.
For camera: The number of native allocations GCs goes from 4 to 2,
improving launch time by 25ms (average of 25 runs on pixel).
The multiplier is 1 for low ram devices, so this should not increase
RAM on devices where it matters.
