Vulkan: Additional "invalidate" white-box tests
These are additional tests that were written when trying to refactor mContentDefined and move it from RenderTargetVk to ImageHelper for depth/stencil attachments. We still want to land the tests. Bug: b/167275320 Change-Id: I12f6bf8cece6499e4474a8f114b177626c1aa4d5 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2419117 Reviewed-by: Shahbaz Youssefi <syoussefi@chromium.org> Reviewed-by: Charlie Lao <cclao@google.com> Commit-Queue: Ian Elliott <ianelliott@google.com>
