i915: Add gem_exec_endless
Start our preparations for guaranteeing endless execution.
First, we just want to estimate the direct userspace dispatch overhead
of running an endless chain of batch buffers. The legacy binding process
here will be replaced by async VM_BIND, but for the moment this
suffices to construct the GTT as required for arbitrary indirect
execution.
