chore: Revert to current date as timestamp for devnet

[spalladino]

When running devnet, using the slot timestamps instead of current timestmap meant that blocks were often generated with a timestamp much into the future. This screwed up settings such as the min and max time between blocks for a sequencer configuration, which relied on L2 timestamps. In addition, the custom block timestamp interval in anvil meant that we could no longer rely on L1 timestamps for measuring time, which was needed for tracking the time between a block being submitted and its proof.

This PR changes timestamps if devnet is set so that we use the current timestamp for building blocks, do not alter anvil's block timestamp, and drop time validations.

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.
