SDL_TriggerBreakpoint() should default to __debugbreak() on Windows platforms

#define SDL_TriggerBreakpoint() __debugbreak()

I'm in CLion using the default settings which are MinGW (gcc/g++). MinGW does implement __debugbreak(), but this configuration evaluates to __builtin_trap() instead.

The __builtin_trap() can't be stepped over in the debugger, so __debugbreak() is superior and should be preferred when available.

I'm assigning myself to this, but someone submitting a PR will get this in revision control sooner than I'll get to it, so don't be shy. :)
