I think the most significant effect is that some configuration parsers:

   * ipa::AgcMeanLuminance::parseConstraintModes: ipu3, mali-c55, rkisp1
   * ipa::AwbAlgorithm::parseModeConfigs: rkisp1
   * ipa::rkisp1::algorithms::Agc::parseMeteringModes: rkisp1
   * ConfigParser::parseLocation: virtual

use the `XYZNameValueMap`s, so this has an effect on configuration files.

Adding the `deprecated` attribute is I think a good idea, but more changes
would be needed to warn about deprecations in the configuration files.
