Reland "Use GrVkMemoryAllocator for vulkan memory allocations in ganesh."

This is a reland of 331c266ed716526478a10885aff66181cec64486

Original change's description:
> Use GrVkMemoryAllocator for vulkan memory allocations in ganesh.
> 
> Besides using the new allocator, the big logical change is that map
> and unmap calls form GrVkMemory are specc'd to map the entire GrVkAlloc
> instead of a specific offset and size as they did before. As a
> consequence of this, we move the handling of non-coherent alignment
> for flush/invalidate calls to GrVkMemory instead of the callers.
