highlighter: Add condition for new vim9 script implementation
Add a new condition that will contain the new vim9script implementation
of the highlighter logic. Not done yet.
To test it out, you need a recent Vim 8.2 and in addition set the
configuration variable
:let g:airline_experimental=1
Implementation for all the functions will follow.
