media: rkvdec: h264: Support High 10 and 4:2:2 profiles

Add support and enable decoding of H264 High 10 and 4:2:2 profiles.

Decoded CAPTURE buffer width is aligned to 64 pixels to accommodate HW
requirement of 10-bit format buffers, fixes decoding of all the 4:2:2
and 10bit 4:2:2 flusters tests except two stream that present some
visual artifacts.

- Hi422FREXT17_SONY_A
- Hi422FREXT19_SONY_A

The get_image_fmt() ops is implemented to select an image format
required for the provided SPS control, and returns RKVDEC_IMG_FMT_ANY
for other controls.
