vulkan/wsi/x11: Destroy Present event context when destroying swapchain
Without this, the X server may accumulate stale Present event contexts if a client creates and destroys multiple swapchains using the same window. v2: Based on Chris Wilson's review: * Use xcb_present_select_input_checked so that protocol errors generated by old X servers can be handled gracefully * Use xcb_discard_reply() instead of free(xcb_request_check()) v3: Rebased on top of this code having been refactored out of anv Reviewed-by: Dave Airlie <[email protected]>
