kernel-doc: allow object-like macros in ReST output

output_function_rst() does not handle object-like macros. It presents
a trailing "()" while output_function_man() handles these macros
correctly.

Update output_function_rst() to handle object-like macros.
Don't show the "Parameters" heading if there are no parameters.

For output_function_man(), don't show the "ARGUMENTS" heading if there
are no parameters.

I have tested this quite a bit with my ad hoc test files for both ReST
and man format outputs. The generated output looks good.
