Marc Mutz aefa427459 qHash(): make 1-to-2-arg adapter a worse match than regular 2-arg overloads
... by adding more arguments, but then constraining that they don't,
actually, exist.

This makes the the signature of a normal qHash(T, size_t) consistently
a better overload (for same T) than the 1-to-2 adapter. It doesn't
solve the problem that the adapter inserts hash functions for types
that were never defined to be hashable (cf. e.g. QTBUG-116076). But
the adapter is already slated for removal in Qt 7, which will solve
the issue, though maybe we can expedite its demise in 6.9.

Add the test from the bugreport to tst_QHashFunctions.

This directory contains autotests and benchmarks based on Qt Test. In order
to run the autotests reliably, you need to configure a desktop to match the
test environment that these tests are written for.

Linux X11:

   * The user must be logged in to an active desktop; you can't run the
     autotests without a valid DISPLAY that allows X11 connections.

   * The tests are run against a KDE3 or KDE4 desktop.

   * Window manager uses "click to focus", and not "focus follows mouse". Many
     tests move the mouse cursor around and expect this to not affect focus
     and activation.

   * Disable "click to activate", i.e., when a window is opened, the window
     manager should automatically activate it (give it input focus) and not
     wait for the user to click the window.
