Refine dependencies and remove unused packages

[kk-hainq]

The main goal is to refine the Nix/Cabal setup and remove unused packages. The followings are completely removed:

• cardano-crypto-tests.
• lobemo-backend-aggregation.
• lobemo-backend-monitoring.
• lobemo-backend-trace-forwarder.
• lobemo-scribe-systemd.
• shelley-spec-ledger (this was used, just replaced with something new).
• shelley-spec-ledger-test (this was used, just replaced with something new).

I went from an empty cabal.project so I took the liberty to draw a dependency updating process, as I think there wasn't a concrete one before. For now:

• Just keep iohk-monitoring-framework as is until upstream updates develop/master that addresses the comment in cabal.project.
• Update plutus when new changes are desired, like better script sizes for plutus-apps demos, tests, and use cases.
• Make flat follow plutus.
• Update servant-purescript & purescript-bridge when new changes are desired.
• Update cardano-wallet when new changes are desired.
• Make these follow cardano-wallet:
  • cardano-node
  • cardano-ledger
  • ouroboros-network
  • cardano-base
  • cardano-prelude
  • cardano-crypto
  • cardano-addresses
  • goblins
  • Win32-network

It is preferred to track a stable node release through cardano-wallet. This PR tracks the latest 1.33.0 release, and naturally resolves #240.

The third commit is updateMaterialized so reviewing the others should be enough.

Pre-submit checklist:

• Branch
  • Tests are provided (if possible)
  • Commit sequence broadly makes sense
  • Key commits have useful messages
  • Relevant tickets are mentioned in commit messages
  • Formatting, materialized Nix files, PNG optimization, etc. are updated
• PR
  • Self-reviewed the diff
  • Useful pull request description
  • Reviewer requested
