libcamera: formats: Expose PixelFormatInfo as an internal API

To prepare for storing more information about pixel formats in PixelFormatInfo, move the class to formats.cpp and document it. The pixel formats database is moved to the same file, and a new static function is added to PixelFormatInfo to retrieve a PixelFormatInfo for a PixelFormat.
