REORG: include: move acl.h to haproxy/acl.h{,-t}.h

The files were moved almost as-is, just dropping arg-t and auth-t from
acl-t but keeping arg-t in acl.h. It was useful to revisit the call places
since a handful of files used to continue to include acl.h while they did
not need it at all. Struct stream was only made a forward declaration
since not otherwise needed.
