Thanks! I added some checks. FlipEx only works in windowed mode and only works with |

Added the option to enable D3DSWAPEFFECT_FLIPEX when using the D3D9Ex API.
This swap effect allows the application to enter Flip Model, which helps reduce latency and even enables support for VRR in borderless mode.
Not every game works well with the conversion to D3D9Ex, but I believe it is a good option to have.
I am not very experienced in this area, so I followed the rules in this Microsoft documentation.
AntiAliasing must be disabled in FlipEx, at least 2 backbuffers are required, and the D3DPRESENTFLAG_LOCKABLE_BACKBUFFER flag cannot be used either, because in Flip Mode DWM needs to access the backbuffer.
