Arch specific ptrace commands for BSDs

This PR is to add architecture specific ptrace requests etc.

Don't merge this yet if it passes I want to go over the other BSDs and architectures to see if I've missed anything I'm just creating the PR to get that initial CI approval that it's right as I expect this bit to be more fiddly.
