Add Brazilian Portuguese language option

[MaNE-17]

Thanks for the port! In future updates, please consider adding a Brazilian Portuguese language option. Currently, the port only supports European Portuguese.

Good news: the game itself ships Brazilian Portuguese (its USpt texts), so it's a matter of asking for it. In v0.1.9:

• the F1 menu's game language list has "Português (Brasil)" (contributed by @GabrielAndrade419);
• on a computer set to Brazilian Portuguese (pt-BR), the game picks it by itself. Until now any Portuguese locale gave European Portuguese.

You can also set MKW_LANG=pt-BR in mkw.ini. Closing this as resolved in v0.1.9.

v0.1.9 is out: a system set to Brazilian Portuguese now picks the game's own Brazilian Portuguese, and the menu has it too. Release: https://github.com/adriadam10/mkw-recomp/releases/tag/v0.1.9
