build: Make ra-modules compiling into shared DLL on Windows with CMake.

This change will only affect CMake build. gen-win still have the previous
behavior.

* build.conf
  (libsvn_ra): Add explicit dependency on APR-Util; before it was inheriting
   from a ra-module.
  (libsvn_ra_serf, libsvn_ra_svn, libsvn_ra_local): Export required headers
   from the libraries.
* CMakeLists.txt
  (options): Make the shared modules to be shared by default also on Windows.
  (checks): Do not warn if enabled shared modules on Windows.
