UI: Update Simple Mode AMD Presets

Due to the default value assigned to AMF.H264.VBVBuffer.Strictness and AMF.H264.Version, the config upgrade code ran every time someone tried to use simple mode. That caused the AMF.H264.VBVBuffer.Strictness value to always be stuck at 100, which is wrong for streaming and recording.
