Stop duplicating supported mimetypes
Since the mimetypes supporte by Ark must be both in the Ark .desktop
file and in the JSON metadata of the plugins, they are currently duplicated in the CMakeLists.txt
file of each plugin.
cmake >= 3.19 supports parsing of JSON files, so we can move those mimetypes directly inside the metadata JSON files of the plugins, and use cmake to parse those files and put the list of all mimetypes in the Ark .desktop
file.
