runtime: make distributed/local malloc stats the source-of-truth This change makes it so that various local malloc stats (excluding heap_scan and local_tinyallocs) are no longer written first to mheap fields but are instead accessed directly from each mcache. This change is part of a move toward having stats be distributed, and cleaning up some old code related to the stats. Note that because there's no central source-of-truth, when an mcache dies, it must donate its stats to another mcache. It's always safe to donate to the mcache for the 0th P, so do that.
