HWUI-VK: Use auto prerotation for Vulkan backend

The consumer driven resizing now works as below:
1. Query the cached transform hint for this draw cycle
2. dequeuBuffer first to get the actual size
3. Cancel the pre-rotation done on the buffer
4. Update logical window size according to the transform

Bug: 136110987
Test: manually test split screen with resizing and rotation
Test: CtsUiRenderingTestCases and CtsGraphicsTestCases
