refactor: aircraft type check

[2hwk]

Fixes #8499

Summary of Changes

This pull request introduces an AircraftType enum to the common module, fundamentally altering the mechanism for aircraft type verification. Previously, this process depended on matching the SimVar Title, a method that proved unreliable due to its reliance on specific search terms which needs to be added by the Livery Creator. This could result in the incorrect loading of build_info.json. With the proposed changes, upon reaching the Ready state, a new SimVar, "L:A32NX_AIRCRAFT_TYPE", will be assigned a value from the AircraftType enum corresponding to the A32NX. This will enable a more reliable comparison against the enum values to determine the appropriate build_info.json prefix (e.g., a32nx, a380x). Furthermore, this PR ensures consistency across the codebase by replacing static string comparisons for airframe checks with enum comparisons. This approach not only improves the current implementation but also allows for the easy integration of additional airframes in the future.
