Bundled Theme: Twenty Nineteen: Use human-friendly color names.

For better accessibility, the Primary and Secondary theme colors have now more understandable names.
Changes the names "Primary" and "Secondary" to "Blue" and "Dark Blue". Fallbacks to the `hex` color codes when the theme is set to use a custom Primary color.

Props kjellr, aduth, audrasjb.
Fixes #46698.
