Fix window not initializing on primary monitor on GLFW backend (#3923)

Browse Source 
The way the current code worked was by calling `GetCurrentMonitor()`,
which would always return the monitor at position (0,0). This isn't the
primary monitor on all platforms, on Linux in particular it isn't the
case.

This isn't the case on the SDL backend, after calling `InitWindow()` the
window would always show up on the primary monitor. Even on the GLFW
backend, if the full screen flag was set it would attempt to put it on
the primary monitor as it would call `glfwGetPrimaryMonitor()` to do it,
so for consistency's sake we should do it on windowed mode too.
