[OpenXR] Swapchains might create multisampled images for no benefit
https://bugs.webkit.org/show_bug.cgi?id=320898
Reviewed by Dan Glastonbury.
createSwapchain() passed the view configuration's
recommendedSwapchainSampleCount straight through to XrSwapchainCreateInfo. That
recommendation is meant for applications that render into the swapchain
image directly. However that image is shared with the WebProcess where
it is rendered. The WebProcess already uses a multisampled renderbuffer
backed by the shared image in order to support MSAA. A multisampled
image from the OpenXR runtime won't add anything.
No new tests as there is no change in behavior.
