intel: overhaul the internal WSI interface
The goal is to hide X11 details from the rest of the driver and move closer to
upstream WSI extensions that are still in development. As a result hiding X11
details, ENABLE_WSI_X11 is unnecessary and is removed.
To move closer to upstream WSI extensions, intel_gpu_associate_x11() is
removed. The X11 connection is available much later in upstream WSI
extensions.
There is also a bug fix. When a fence is used like this
xglQueuePresent(..., fence);
xglQueueSubmit(..., fence);
xglWaitForFences(..., &fence);
it will (correctly) wait for the present to finish before waiting for the
command buffer.
