Allow static libs

- Remove SHARED option from add_library to allow static libs,
  CMake then respects the standard BUILD_SHARED_LIBS option.
- Set the default value of BUILD_SHARED_LIBS to ON.
- Modify plugin_manager_impl to call the plugin init function
  for built-in plugins via a hook, whilst still supporting
  external shared library plugins.
- Add plugin init hook function to each built-in plugin.
- Add plugin libs to link libs in CMake export config when
  static libs are enabled.
