anv: support GetSwapchainGrallocUsage2ANDROID for Android

New function supports gralloc1 usage flags that get set separately for producer and consumer. As we still need to support old method too, let's share common code and use android_convertGralloc0To1Usage helper. Bump the VK_ANDROID_native_buffer version to indicate support for the new call.

Changes were tested on Android Celadon P with Basemark GPU and various Sascha Willems Vulkan demos.
