Missing extension op definitions

[aborgna-q]

Followup to #366. We define many ad-hoc operations as opaque ops in a "guppylang.unsupported".
Some of these are missing from hugr's std extensions, or not exposed in hugr-py. Others may need to be defined as local extensions.

• list and array ops. (MakeList, see other ops in guppylang.prelude.builtins)
  • Add list ops to hugr.
    Add more list operations hugr#1467
  • Add array ops to hug.
    Fill out array ops hugr#1320
  • Convert between usize and int<N>.
    Add std operations to convert between arithmetic.ints and usize hugr#1472
  • Implement CustomOpCompilers for list builtins #460
• Replace guppylang.unsupported ops with new hugr definitions #411.
  • feat: Add missing ops hugr#1463

  • Use extOps definitions from hugr-py 0.8 #412
• Support ifrombool / itobool for arbitrary ints #409
  • Converting bool to int doesn't work #281

• Tket2 ops.
  • Create serialized extension definitions tket2#556 Temporarily hard-coded the extension jsons into guppy
  • Drop the local validator #390
