Decrease lock uses in RosAlloc::BulkFree().
Read rosalloc page map entries without a lock.
Disabled for now.
This change speeds up Ritz MemAllocTest by ~25% on host and reduces
the GC sweep time, but somehow slows it down by ~5% on N4, which is
why it's disabled for now. TODO: look into the slowdown on N4 more.
