Define a collection of bits for different types of capture file comments.

For each capture file type, have a bitset of comment types supported by
that capture file type.

Add a Wiretap routine that, for a given file type, returns the bitset of
comment types it supports.

Have wtap_get_savable_file_types() take a bitset of comment types that
need to be supported by the file types it returns.

Replace cf_has_comments() with a routine that returns a bitset of
capture file comment types in the capture file.

Use those routines in the capture file dialogs; don't wire in the notion
that pcap-NG supports all comment types and no other file formats
support any comment types.  (That's currently true, but we don't want to
wire that in as being forever true.)
