Add support for track_tags and global tags in MKVFile

[rcolfin]

Currently global_tags and track_tags are an internal implementation detail of the mkv.info_json. Expose these properties in the pymkv.MKVFile instance. In this case, if one wants to strip out this detail based on whether it is specified in the mkv file, one needs to do the following:

    mkv_info_json = cast(dict[str, Any], mkv._info_json or {})  # noqa: SLF001
    if mkv_info_json.get("global_tags"):
        no_global_tags = True

    if mkv_info_json["track_tags"]:
        no_track_tags = True
