runtime: fix stale comment for mheap/malloc
mheap use pageAlloc to manage free/scav address space instead of
using free/scav treap. The comment on mheap states mheap uses
treaps. Update the comment to reflect the use of pageAlloc.
In the fallback code when sizeSpecializedMalloc is enabled,
heapBitsInSpan is false. Update the comment to reflect that.
