eth/tracers: add disableCode/Storage options for prestateTracer (#30648)
When using the prestateTracer, in some cases users are only concerned with balances or nonce information, and are not interested in the lengthy contract code or storage data. Therefore, this PR introduces two new configuration options in the `prestateTracerConfig` structure: - `disableCode` - `disableStorage` These options allow users to control whether the tracer returns contract code and storage data during execution tracing. By setting these options, users can more flexibly customize their needs and focus on obtaining information that is more critical and relevant to their specific use cases. These options work with the default mode as well as `diffMode: true`. --------- Signed-off-by: jsvisa <[email protected]> Co-authored-by: Sina M <[email protected]>
