WIN32: Add a default application manifest

This fixes an OpenGL renderer issue for builds with MSYS2/Mingw64 or MSYS2/Mingw32

The issue pertains to MSYS2 adding a default manifest file (default-manifest.o) to the executable

The bug is for PC systems with GPU drivers that were not properly supported for Windows 10 
systems, like Intel HD Graphics series 1st and 2nd generations. In those systems, launching a 
game in ScummVM (built with MSYS2/Mingw) with the OpenGL renderer would cause the game 
screen to be a white blank image, and various warnings would be output to the console, eg.
"WARNING: GL ERROR: GL_INVALID_ENUM on glTexSubImage2D(0x0DE1, 0, 0, area.top, src.w, area.height(), _glFormat, _glType, src.gere.cpp:167)!"
This was due to MSYS2/Mingw builds trying to load the (poorly supported) GPU driver while advertising support for Windows 10 in their
embedded default Manifest file. Hence, the GPU driver DLL (eg ig4icd64.dll) would be unloaded, causing the bug.
