TextEditor: Fix folding for async syntax highlighter

Browse Source 
- Made restoreState, ensureBlockIsUnfolded, fold, unfold and unfoldAll
functions to be called only after highlighting is done
- Improved management of foldValidator in async case
- Removed optimizations in cpphighlighter and glshighlighter.
The highlighters are async now and optimization is not necessary.
In these optimizations in the function highlightBlock the highlighting
changes not only for currentBlock but and for several next. Which is
contradict with the function name.
