vulkan: Add gralloc1 usage to VK_ANDROID_native_buffer

Replaces the gralloc0-style 'int' usage in
vkGetSwapchainGrallocUsage2ANDROID and VkNativeBufferANDROID with a
gralloc1-style pair of uint64_t usages. A later change will plumb this
to and from ANativeWindow; for now we just collapse and expand from
32-bit usage.
