Emulator

Steps to reproduce:

1. Use a localized version of Dolphin (i.e. not English).
2. Press the Controllers button to go to the controller configuration.
3. Press Configure on any controller that supports being configured (for instance an Emulated Wiimote).
4. Right-click on any of the buttons that can be configured.
5. The details window will appear. Look at the text on the button in the bottom-right corner (or bottom-left corner if you're using an RTL language).

The button always says "Apply" in English, but it should say the equivalent of "Apply" in the selected language. Tested in 4.0-8183.

The button appears to be created using CreateButtonSizer. What I don't understand is why https://github.com/dolphin-emu/dolphin/blob/584ea8b3205f703b09f7f030493150e9e526b604/Source/Core/DolphinWX/InputConfigDiag.cpp#L1074 gives a localized Cancel button while https://github.com/dolphin-emu/dolphin/blob/584ea8b3205f703b09f7f030493150e9e526b604/Source/Core/DolphinWX/InputConfigDiag.cpp#L631 gives a non-localized Apply button.
