Use QTextCharFormat::fontFixedPitch to remember Markdown backtick spans
If the editing app (like qtbase/examples/widgets/richtext/textedit)
has controls only for setting a specific font, and someone uses it to
write markdown "from scratch", then we need to detect that they chose
Courier or some other fixed-pitch font, and write the backticks,
because Markdown has no syntax for selecting a specific font family.
If the user loads markdown into such an application, the font
is set to QFontDatabase::systemFont(QFontDatabase::FixedFont).
Round-trip editing was already working, as long as such a font exists.
QTextCharFormat::setFont() calls setFontFixedPitch(font.fixedPitch()),
but for the chosen "mono" font, font.fixedPitch() can be false.
For semantic completeness and separation of concerns, we now
set fontFixedPitch explicitly if a `backtick` span is encountered.
As a followup to f1e60de66540b198d696253ab5148de4fcbff319 this
should get its autotest passing reliably.
Fixes: QTBUG-99676
