tests: fix some -Wvolatile
C++20 deprecated compound volatile statements such as pre- and
post-increments, to stress that they're not atomic. So instead of
volatile i;
~~~~;
++i;
you're now supposed to write
volatile i;
~~~~;
int j = i; // volatile load
++j;
i = j; // volatile store
which matches more closely what hardware does.
Instead of fixing every use of volatile pre- or post-increment in this
fashion individually, and realising that probably a few more Qt
modules will have the same kind of code patterns in them, write
QtPrivate functions to do the job centrally.
