runtime(python): highlight "self" and "cls" in syntax script

These are special names by convention, and giving them distinct
highlighting is a nice visual clue (using Identifier by default).

This group is named "pythonClassVar" to match the name used by
python-syntax. Some third-party color schemes are aware of this
name and customized their colors accordingly.

closes: #17968
