Veer: Bring SBY file in line with doc examples

- Rename to `veer.sby`.
- Remove `fail` task.
- Add `--keep-going` to bmc.
- Reduce setup assumptions.
- Rename `bind.sv` to `formal.sv`.
- Remove memory size limits in `pdr` in favour of cutpointing the memory.
- Bring script section in line with `docs/source/_examples/veer_*.sby`.
