refactor: replace token note with uint note
In this PR, we are replacing the token note with our previously added U128 note and making BalanceSet hold a UintNote instead of being generic. The token note is now redundant as we have a UintNote in aztec nr now.
Resolves #8107.

Benchmark results
Metrics with a significant change:
- protocol_circuit_simulation_time_in_ms (private-kernel-tail-to-public): 1,491 (+94%)
- avm_simulation_time_ms (Token:mint_public): 468 (+856%)
- avm_simulation_time_ms (Token:assert_minter_and_mint): 44.9 (-90%)
Detailed results
All benchmarks are run on txs on the Benchmarking contract on the repository. Each tx consists of a batch call to create_note and increment_balance, which guarantees that each tx has a private call, a nested private call, a public call, and a nested public call, as well as an emitted private note, an unencrypted log, and public storage read and write.
This benchmark source data is available in JSON format on S3 here.
