Minor - Adds build versioning to the engine - V14.1.0

Implements a build versioning system to track and display the engine's build information.

- Adds a version header file defining version constants.
- Increments the build number automatically from a configuration file on each build in the binary folder.
- Displays the build version in the ImGui menu bar for easy identification.
- Persists version information by reading/writing to the config file

This provides better tracking and identification of specific engine builds.
