treewide: remove unnecessary inclusions of parse-options.h from headers

The headers 'diagnose.h', 'list-objects-filter-options.h',
'ref-filter.h' and 'remote.h' declare option parsing callback
functions with a 'struct option*' parameter, and 'revision.h' declares
an option parsing helper function taking 'struct parse_opt_ctx_t*' and
'struct option*' parameters.  These headers all include
'parse-options.h', although they don't need any of the type
definitions from that header file.  Furthermore,
'list-objects-filter-options.h' and 'ref-filter.h' also define some
OPT_* macros to initialize a 'struct option', but these don't
necessitate the inclusion of parse-options.h in these headers either,
because these macros are only expanded in source files.

Remove these unnecessary inclusions of parse-options.h and use forward
declarations to declare the necessary types.

After this patch none of the header files include parse-options.h
anymore.

With these changes, the build time after modifying only
parse-options.h is reduced by about 30%, and the number of targets
built is almost 20% less:

  Before:

    $ touch parse-options.h && time make -j4 |wc -l
    353

    real    1m1.527s
    user    3m32.205s
    sys	    0m15.903s

  After:

    289

    real    0m39.285s
    user    2m12.540s
    sys     0m11.164s
