Initial game localization implementation

[Ryan089]

Summary

Implements a bare-bones localization framework, and demonstrates the concept using the Examine system.

This feature includes:

• the Unity Localization package.
• support for four languages: English, French, Portuguese and Russian. Languages selected to align to key project contributors.
• a few translations courtesy of Google Translate. There's not enough to actually use in-game, but rather a few key tiles / items easily visible on default map to demonstrate that the implementation actually works.
• a note to inform user of missing localization data to support development.
• automated asset audit test to confirm that a localization table has been set for each Examine Data.

PR checklist

• The game builds properly without errors.
• No unrelated changes are present.
• No "trash" files are committed.
• Relevant code is documented.

Testing

Play the game, hover over some of the objects in the default scene to see their name appear in English. Then change language to French or Portuguese, and do the same. Notice that they are different.

To view the localization tables in the editor, go to Windows > Asset Management > Localization Tables. In the Edit Table Collection tab, select the desired Table Collection (currently Tiles, Items or Misc). Tiles is the most populated currently. Check the translations provided in the columns below.

Changes

Updated Examine Data to include a localization table. Aiming to keep these tables pretty high-level. E.g. Tiles, Items, UI etc.

Examine Data Name Key and Description Key are used to refer to an entry in the localization table. They are not intended as the actual display name.

Examine UI now uses the localization tables rather than the key directly.

Known issues

• Although a Russian translation is provided, the text does not appear when Russian is selected. I suspect the specific font asset used does not support Cyrillic.

• Translations are from Google Translate, and are probably wrong.

• Only a very few items actually have translations provided.
