Make IDB settings work sync with JSPI

IndexedDB version of QSettings will now use solely the sync versions
of data access functions. Those will suspend with JSPI.
This makes IDB settings conform to the QSettings contract - and also
allows us to enable tests in tst_qsettings for the IDB version of
QSettings.
Also, do not treat the IndexedDB format as one defining read/write
functions in QSettings - those are the same as for ini format, as
IndexedDB settings backend uses a backing ini file.
