media: mediatek: vcodec: Use 4K frame size when supported by stateful decoder

After commit b018be06f3c7 ("media: mediatek: vcodec: Read max resolution
from dec_capability"), the stateful video decoder driver never really
sets its output frame size to 4K.

Parse the decoder capability reported by the firmware, and update the
output frame size in mtk_init_vdec_params to enable 4K frame size when
available.
