anv: optimize the implicit fencing support of external memory

Browse source 
Previously we apply implicit sync to all external memory, which is a bit
redundant since we only need it for the dedicated image scenario (media
image imported into Vulkan). This change optimizes just like that while
also excluding wsi which has its own way of synchronizing with the
compositor.
