Extend cmake config files with deps, version, etc. (#2916)

This improves how the installed CutterConfig.cmake can be used for
native plugin development:
* Transitive dependencies are resolved automatically
* Version file is included
* Cutter_USER_PLUGINDIR is set to a path that plugins can use as a
  default install destination

src/plugins/sample-cpp/CMakeLists.txt is an example for how to use it.
Rizin was also updated to prevent an error with multiple
`find_package()` calls.
