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.
