venus: expose KHR_external_fence/sempahore_fd extensions

Browse source 
Re-purpose renderer has_external_sync to cover explicit sync emulation
in venus, so that we don't have to add a new flag to distinguish the
emulation path enablement for virtgpu and vtest.

This is to unblock zink implicit sync hanlding against venus for now,
and soon we should migrate to virtgpu fence passing.
