agx: Use a transfer graph for parallel copies

Lifted from ir3. Algorithm is the same; the data structures and interface are
lightly modified to decouple from ir3's IR.

Sequentializing parallel copies after RA is tricky. ir3's implementation works
well enough, so I use that one.

Original implementation by Connor Abbott.
