Implement buffer memory requirement for VK_KHR_maintenance4

The VK_KHR_maintenance4 includes this new requirement:
"Add a guarantee for buffer memory requirement that the size
 memory requirement is never greater than the result of aligning
 create size with the alignment memory requirement."

In order to respect this requirement, the 15 byte padding used
for images and buffers has been instead moved to VkDeviceMemory.
