When using software rendering with the Wayland WSI we should not try to
use explicit sync even if it is supported by the compositor. Not only is
it not necessary in that case, but the protocol explicitly disallows
using it with shared memory buffers.
As a fix, first we modify wsi_configure_cpu_image to not set
info->explicit_sync to true for CPU images. However, we still want the
implicit_sync parameter in wsi_create_buffer_blit_context to be set to
false since CPU images don't need implicit sync either. To ensure that
remains so, we add a new field to wsi_image_info tracking the image
type, and then only enable implicit sync for DRM images when explicit
sync is not supported.
Additionally, we modify wsi_wl_use_explicit_sync to return false when
device->sw is true.
