libcamera: formats: Search PixelFormatInfo on multiple formats

The PixelFormatInfo::info(const V4L2PixelFormat &format) function
returns the PixelFormatInfo associated with a V4L2 pixel format.

As we prepare to associate multiple V4L2 formats to a single
PixelFormatInfo rework the function to search the given V4L2 format
in a list.
