[RESEND, v4] media: mediatek: vcodec: Fix v4l2 compliance decoder cmd test fail

[Yunfei Dong <yunfei.dong@xxxxxxxxxxxx>]

Will return -EINVAL using standard framework api when test stateless
decoder with cmd VIDIOC_(TRY)DECODER_CMD. Disable them to adjust v4l2
compliance test for user driver(GStreamer/Chrome) won't use decoder cmd.
