highlighter: Add condition for new vim9 script implementation

Browse Source 
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.
