Add sk_malloc_size() to query usable allocation sizes
The implementation in SkContainers.cpp tries to use a platform-dependent
way of figuring out the actual size allocated for a memory block, but
when using a custom allocator it should not assume how to obtain this
information. Instead, add a sk_malloc_size() function that custom
allocators can implement.
Existing code gets moved to SkMemory_{malloc,mozalloc}.cpp into their
respective sk_malloc_size() implementations.
