venus: workaround an ANGLE assumption on FORMAT_IMPLEMENTATION_DEFINED
ANGLE expects VK_FORMAT_UNDEFINED to be returned for such AHB prop query.
Workaround that is easier for us.
TEST:
- android.graphics.cts.BasicVulkanGpuTest
- android.graphics.cts.MediaVulkanGpuTest
- android.graphics.cts.CameraVulkanGpuTest
With ANGLE:
- android.graphics.cts.CameraGpuTest
- camera app using custom gl pipelines work normally
