fix: restore dev-dependencies for clippy --all-targets --all-features

Uncomment dev-dependencies that were previously commented out to break
circular dependencies. These dependencies are needed for tests to compile
when running clippy with --all-targets --all-features.

Changes include:
- pezkuwi/node/*: Add pezkuwi-node-subsystem-test-helpers, pezkuwi-primitives-test-helpers
- pezkuwi/xcm/*: Add pezpallet-xcm, xcm-pez-simulator
- pezcumulus/client/*: Add test client, runtime, and sproof builder deps
- bizinikiwi/pezframe/*: Add bizinikiwi-test-utils, pezframe-support-test,
  pezpallet-transaction-payment, pezpallet-example-basic, etc.
- vendor/pezkuwi-zombienet-sdk: Fix imports from zombienet_sdk to pezkuwi_zombienet_sdk

All runtime-benchmarks feature flags have been updated accordingly.

cargo clippy --all-targets --all-features --workspace now passes.
