Fix Vulkan buffer barriers to use VK_WHOLE_SIZE

Buffers are padded to be at least 4 bytes. Dawn would
produce invalid barriers for buffers that were "zero"
bytes large. The size for the barrier must be either
non-zero or VK_WHOLE_SIZE. Since we always intend
to transition the entire buffer, simply use
VK_WHOLE_SIZE instead of GetSize() as the size.
