[bump] Win32: reset deadkeys in StartTextInput/StopTextInput

SDL Development
1

Hi, was wondering if I could get this reviewed / merged before 2.0.5:
https://bugzilla.libsdl.org/show_bug.cgi?id=3332

With the patch applied, Win32 deadkey behaviour across
SDL_Start/StopTextInput matches OS X.
(As an aside, last time I checked, dead keys are broken on X11:
https://bugzilla.libsdl.org/show_bug.cgi?id=2071 )

Thanks
Eric
