Ignore zero properties for MemoryInfo

[SimonCropp]

WriteNumberIfNotZero since on OS that dont implement all props, thos props are stubbed out to zero

[bruno-garcia]

I wonder if there's some API we can call that will tell us whether GetGCMemoryInfo returns meaningful data or not. I mean: When do we get all zeros/defaults?
