FROMLIST: anv/android: handle storage images in vkGetSwapchainGrallocUsageANDROID

Android P and earlier expect that the surface supports storage images, and
so many of the tests fail when the framework checks for that support. The
framework also includes various image format and usage combinations that are
invalid for the hardware.

Drop the STORAGE restriction from the HAL and whitelist a pair of
formats so that existing versions of Android can pass these tests.

Fixes:
   dEQP-VK.wsi.android.*
