contracts: Move Schedule from Storage to Config (#8773)
* Move `Schedule` from Storage to Config * Updated CHANGELOG * Fix nits from review * Fix migration * Print the debug buffer as tracing message * Use `debug` instead of `trace` and update README * Add additional assert to test * Rename `schedule_version` to `instruction_weights_version` * Fixed typo * Added more comments to wat fixtures * Add clarification for the `debug_message` field
