media: mediatek: vcodec: record capture queue format type

The capture queue format type may be differ depending on platform: for
stateless decoder drivers, we need to calculate the capture buffer size
according to the capture queue format type in SCP.

As a preparation for introducing drivers for stateless decoding, save the
current capture queue type on a per vcodec context basis.
