Subject: Port Q_STATIC_ASSERT(_X) to static_assert

There is no reason for keep using our macro now that we have C++17.
The macro itself is left in for the moment being, as well as its
detection logic, because it's needed for C code (not everything
supports C11 yet).  A few more cleanups will arrive in the next few
patches.

Note that this is a mere search/replace; some places were using
double braces to work around the presence of commas in a macro, no
attempt has been done to fix those.

tst_qglobal had just some minor changes to keep testing the macro.
