eth/tracers: Adds codeHash to prestateTracer's response (#32391)

**Problem:** Including full account code in prestateTracer response
significantly increases response payload size.

**Solution:** Add codeHash field to the response. This will allow
client-side bytecode caching and is a non-breaking change.

**Note:** codeHash for EoAs is excluded to save space.
