[core,settings] unify configuration paths
* Add new function freerdp_settings_get_config_path to get current
  user configuration directory
* Add CMake option WITH_FULL_CONFIG_PATH (default OFF): If defined, use
  <appdata>/Vendor/Product as config directory, otherwise use
  <appdata>/vendor (lowercase, only if vendor equal to product)
