[PATCH v10 0/1] MR6131: Extend bcp47langs.dll with GetUserLanguages

[Marius Schiffer (＠MariusSchiffer)]

This is an undocumented API used by some programs to
fetch the user's selected languages.

Example is Fusion360 (during its login process).

Signature currently taken from here: https://stackoverflow.com/questions/63877075/what-is-the-right-way-to-get-th...
(Maybe that stackoverflow answer is also why Fusion has implemented this...)
