Media: Fall back to available icons if SVG media icons not found.
Follow up to [57687]. If no icons of the preferred type are available, then the icon array should return the collection of valid icons found, rather than an empty array. Props dglingren, sabernhardt, swissspidy, sabernhardt, antpb, joedolson. Reviewed by swissspidy. Merges [57845] to the 6.5 branch. Fixes #60740.
