Doc: Part 1 Fix Qt Multimedia documentation issues

TODO:
    * src/multimedia/audio/qaudiobuffer.cpp:333: (qdoc) warning: Cannot find 'QAudioBuffer::StereoFrame'
    * multimediaquick/camerafocus.qdoc content refers to now-removed classes
    * multimediawidgets module doc needs CMake build instructions/snippet
    * Lots of undocumented parameters, enum values, other minor things

Pick-to: 6.2
