swig-rb: Add type casting for some generic function pointers

With r1915236 and this commit, we can build swig-rb by using clang 16
without masking int-conversion and incompatible-function-pointer-types
errors.

* subversion/bindings/swig/ruby/libsvn_swig_ruby/swigutil_rb.c
  (svn_swig_rb_set_pool, svn_swig_rb_set_pool_for_no_swig_type,
  svn_swig_rb_to_apr_array_row_prop, svn_swig_rb_to_apr_array_prop,
  r2c_hash, invoke_callback, callback_handle_error,
  invoke_callback_handle_error, svn_swig_rb_set_baton):
   Add type casting for generic functions in Ruby C API functions. 
  (svn_swig_rb_hash_to_apr_hash_swig_type):
   Add type casting for generic function on apr_hash_t
