Removes a bug introduced in v1.2.3: the DLSS clip-space jitter block was emitted into every vertex shader and read the Position output before writing it. Reading an unwritten output is undefined, so vertex positions could come out as garbage - whole 3D passes landing nowhere (the green screen reported on GYLT, Ghostbusters, Blair Witch and others) and the black block artifacts in Xenoblade Chronicles 2's motion-blur pass, which had been mistaken for a long-standing emulation defect and worked around by disabling the effect. With jitter off - how this fork ships - the vertex epilogue is now identical to the base emulator again, and the motion blur no longer needs to be disabled. CodeGenVersion bumped so existing shader caches are rebuilt. Also adds a DLSS sharpening slider (0-100, off by default) and an experimental advanced motion stack checkbox (off by default).
