pipe-loader: Add kmsro pipe_loader target
kmsro is used by numerous embedded GPUs for a common winsys abstraction.
Let's add support for it for the dynamic pipe loader, so clover can
probe on these drivers.
We build the target with Panfrost. When other drivers need kmsro+clover,
we can revisit the build system part; my mesonfu is wanting.
