[Feature request] Ignore Windows Keyboard Language Influence On Pads

[sampletext32]

I've got Windows 10 with Russian Localization and while I'm without an actual gamepad I've had to do some tests with keyboard as a PAD.
I found out that RPCS3 completely ignores my keyboard clicks when it's not in english.
Easy auto-fix - set keyboard language to english.

I think this is kind of annoying, it took me a couple of minutes to figure out why my pads aren't working. I think that emulation should work with any kind of keyboard, no matter of system language.

Here is my pads setup.

I've been doing tests with [BCES01585] but I think it's irrelevant for this kind of problem.

Here is a log, as requested, but I think, it's also irrelevant.

My bad. But quick lookup over repository showed nothing, so - decided to open.
