Clean up after enabling per-window-input-rotation

The input feature of per-window-input-rotation is now enabled by
default. Since we don't want to maintain two pipelines for input
rotation, we remove the old code path and clean up accordingly.

Bug: 188939842
Test: presubmit
Test: manual, test that touch and mouse works with display rotated
