Use an elapsed timer in the syntax highlighter to periodically return
from the highlight and push a continue highlight to the end of the event
loop.
This allows the user to interact with the editor in between those
batches. If the user modifies the document in between highlighting
batches, the area that still needs a rehighlight is increased if needed.
This also reverts 62ea85ee6a and the
related changes.

since the async highlighter implementation the parent is not a
TextDocument anymore, but a QTextDocument. Pass the required mimeType
via the SyntaxHighlighterRunner now to the SyntaxHighlighter.

This change involves the relocation of SyntaxHighlighter processing
to another thread. The core idea is to create a duplicate of the
original TextDocument using SyntaxHighlighterRunnerPrivate::cloneDocument.
A new SyntaxHighlighter is then instantiated by SyntaxHighLighterCreator
for the cloned document. The entire SyntaxHighLighterCreator class is
moved to a new thread, where it performs highlighting on the cloned
document. Upon completion of the highlighting process, the resultsReady
signal is emitted, and the updated highlighting data is applied to the
original document.
This shift of SyntaxHighlighter to another thread enhances the user
experience by preventing UI slowdowns during the highlighting process.
- Introduction of BaseSyntaxHighlighterRunner as an interface class for
future *SyntaxHighlighterRunner.
- Inclusion of DirectSyntaxHighlighterRunner class for performing
highlighting in the main thread, suitable for syntax highlighters
that cannot be moved to another thread.
- Introduction of ThreadedSyntaxHighlighterRunner class for highlighting
in a separate thread, preventing UI blocking during the process.
- Addition of Result data to the SyntaxHighlighter class to facilitate
data exchange between threads.

Tests that create a QApplication need to be started with
"-platform minimal" so that they won't fail on build servers
without Display.
This also keeps them from distracting you if you run them while working.
