[PATCH v6 0/3] MR10504: vbscript: Implement GetLocale / SetLocale and honor locale in Format*

[Francis De Brabandere (＠francisdb)]

Implements `GetLocale` and `SetLocale` (previously stubbed as `E_NOTIMPL`) and makes the locale-sensitive `Format*` built-ins actually respect the script's current locale.

This mimics the jscript implementation.
