Add MetaAnonymousFile, an abstraction around anonymous read-only files. Files can be created by calling meta_anonymous_file_new(), passing the data of the file. Subsequent calls to meta_anonymous_file_open_fd() return a fd that's ready to be sent over the socket. When mapmode is META_ANONYMOUS_FILE_MAPMODE_PRIVATE the fd is only guaranteed to be mmap-able readonly with MAP_PRIVATE but does not require duplicating the file for each resource when memfd_create is available. META_ANONYMOUS_FILE_MAPMODE_SHARED may be used when the client must be able to map the file with MAP_SHARED but it also means that the file has to be duplicated even when memfd_create is available. Pretty much all of this code was written for weston by Sebastian Wick, see https://gitlab.freedesktop.org/wayland/weston/merge_requests/240.
