Vulkan: Rotate damage rects for 90/270 rotation

ANGLE supports the EGL_KHR_swap_buffers_with_damage extension by using the Vulkan-equivalent VK_KHR_incremental_present extension. The damage rectangles need to be rotated for 90/270-degree rotations. Test: Aztec Ruins with VVL Bug: b/157667116 Change-Id: I9a43594b30bc67ca80aeff7705b4350659207d09 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2289035Reviewed-by: Courtney Goeltzenleuchter <courtneygo@google.com> Reviewed-by: Cody Northrop <cnorthrop@google.com> Commit-Queue: Ian Elliott <ianelliott@google.com>
