libcamera: formats: Fix warning for unknown V4L2 pixfmt
Commit f25ad4a2b16b ("libcamera: formats: Reimplement V4L2 PixelFormatInfo::info()") changed the PixelFormatInfo::info(const V4L2PixelFormat &format) function overload to: return info(format.toPixelFormat()); As part of the series that contains such commit, the PixelFormatInfo for the pixel format applied to a video device is now retrieved at V4L2VideoDevice::open() time. Some video devices register formats not available to applications, for example metadata formats or, in the case of ISP devices, formats to describe the ISP statistics and parameters. This causes the format.toPixelFormat() call to output a WARN message, which spams the log and unnecessarily alerts the users. Augment V4L2PixelFormat::toPixelFormat() with an optional argument to suppress warnings in the case a V4L2 pixel format is not known, to restore the behaviour preceding commit f25ad4a2b16b and returns an invalid PixelFormatInfo without outputting any unnecessary warning message.
