Clear zygote space cards for CC
There may be dirty cards from reference processing or from zygote
compaction. Having these dirty cards in the zygote space is
unnecessary and causes PSS increase from GrayAllDirtyImmuneObjects
in future GCs. Clearing the zygote space cards when the zygote
space is created fixes this issue and reduces PSS.
System wide PSS for zygote space, before:
