   avformat/iamf_parse: fix parsing of Scalable layouts with Mono and Stereo layers
   An ASAN heap-buffer-overflow in scalable_channel_layout_config was caused by an
   unchecked assumption that the channel layout of a scalable audio layer is a
   superset of the previous layer's channel layout.
   
   scalable_channel_layout_config constructs a channel layout map by copying
   channels from the previous layer and adding new ones. The memory allocation is
   based on the target loudspeaker_layout. However, if the target layout doesn't
   encompass all previous channels (e.g., Mono to Stereo), copying previous
   channels followed by adding current ones could exceed the allocated size,
   causing a heap buffer overflow.
   
   This commit adds an exception for the know case of Mono -> Stereo, and a check
   to ensure the previous layer's channel layout is a subset of the current
   layer's layout by comparing their masks. If the condition isn't met,
   an error is returned.
