ResourceSimpleList/SimpleList: write correct capacity value

[carmineos]

Seems that blocks SimpleList64<T> always have the Capacity field set to 1 when the array is empty.
ResourceSimpleList32_64<T> instead seems to always have an array of Capacity > Count (not exactly equals), infact BVHNodes array has some nodes left to read although they seem to be all zeroes except for a field set at 1 (defualt init of a value type?), should we read (and write back) them too?
