Reload settings when the input method changes

[lhecker]

VkKeyScanW as well as MapVirtualKeyW are used throughout
the project, but are input method sensitive functions.

Since #10666 win+sc(41) is used as the quake mode keybinding,
which is then mapped to a virtual key in order to call RegisterHotKey.
This mapping is highly dependent on the input method and the quake mode
key binding will fail to work once the input method was changed.

PR Checklist

• Closes Reload locale specific data when the input language or method changes #10729
• I work here
• Tests added/passed

Validation Steps Performed

• win+` opens quake window before & after changing keyboard layout ✔️
• keyboard layout changes while WT is minimized trigger reloaded ✔️

I added the two new files using Visual Studio instead of adding them by hand. Hence all these changes.
But I looked at them and thought that it's actually an appropriate cleanup and left it in this PR.

This won't fix #10875 by itself, right?

@zadjii-msft No. We could remove the ScanCode field from KeyChord, but this would break serialization. As such, I believe, we’re forced to make ActionMap not use KeyChord anymore, but a custom type which doesn’t have ScanCode instead.
