Implement Overworld Map Inspection Commands

- Added `OverworldDescribeMap` command to summarize metadata for a specified overworld map.
- Introduced `OverworldListWarps` command to list overworld entrances and holes with their coordinates.
- Refactored existing `overworld.cc` to utilize new helper functions for parsing and validation.
- Created `overworld_inspect.cc` and `overworld_inspect.h` to encapsulate map and warp-related functionalities.
- Updated `ModernCLI` to register new commands and handle their execution.
- Modified `tool_dispatcher.cc` to support dispatching the new commands.
- Updated CMake configuration to include new source files for the inspection commands.
