Masayuki Nakano d450beac6f Bug 1191862 - part 1: Make nsIWidget::NativeKeyBindingsType independent from nsIWidget and defined in an independent header file r=smaug
I'd like to use it in `IMEData.h`.  However, adding new include into it may
cause bustage with MinGW, and it's included by `nsIWidget.h` because `nsIWidget`
requires some classes defined in `IMEData.h`.  Therefore, I'd like to make a
new header file for avoiding the include hell.
