Qt5 work around for suzhou numerals

Browse Source 
When windows is told to display Standard digits as suzhou, it is showing
incorrect information in yuzu, file sizes and the CPU speed limiter are
effected by this. See #8698 for some screenshots.

Setting number format to Chinese (Simplified, Hong Kong SAR) is one
way to see this issue in action.

Fixes #8698
