include: linux: Add MediaTek pixel formats

Add the MediaTek-specific pixel format for the MT8183 Pass1 ISP. The
formats have been posted to the linux-media mailing list in the
following patch.

    media: pixfmt: Add Mediatek ISP P1 image & meta formats

    Add packed/full-g bayer formats with 8/10/12/14 bit
    for image output. Add Pass 1 (P1) specific meta formats for
    parameter processing and 3A/other statistics.

    (The current metadata format used in meta input and partial
    meta nodes is only a temporary solution to kick off the driver
    development and is not ready to be reviewed yet.)
