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.

This does the analog of 46f407126e for the
methods we care about (signals, slots, Q_INVOKABLEs). In addition to the
actual QMetaType, we store an array with offsets so that we later can do
a mapping from methodIndex to metatype.
The newly added QMetaMethod::{return,parameter}MetaType methods can then
be used to retrieve the metatypes.
This does however require that all involved types are complete. This is
unfortunately not a feasible requirement. Thus, we only populate the
metatype array on a best effort basis. For any incomplete type, we store
QMetaType::Unknown. Then, when accessing the metatype, we fall back to
the old string based code base if it's Unknown.
Squashes "moc: support incomplete types" and "Fix compile failures
after QMetaMethod change"

Use P0608's trick to detect convertibility without narrowing;
and now that we can depend on C++17, use its features.
First, this moves the burden of detecting a narrowing conversion on
the compiler, rather than us maintaining a complicated series
of checks. Of course, this exposes
* bugs in compilers (e.g. GCC < 9 thinks that float->bool is not
narrowing;
* behavior still not (widely) implemented (pointer to bool
conversions are narrowing, P1957);
* interesting compiler choices, e.g. GCC 9 thinks that unscoped
enumerations are non-narrowing convertible to a datatype big
enum to contain all the _enumerators_, even if the underlying
type of the enum (and/or its sizeof()) is wider than the target
datatype.
Second, it allows to detect conversions that have a narrowing
conversion as an intermediate step. Given a type like
struct Bad { operator double() const; };
then an object of type Bad is implictly convertible to a type
like int via a narrowing conversion. Therefore, a connection
is possible between a signal carrying a Bad and a slot accepting
an int. We can now detect and block this.
Tests regarding scoped enumerations have been dropped,
for the simple reason that a scoped enumeration is not
implictly convertible to an integral type, so we don't have
that detection (it would constantly fail). Scoped enumerations
do not take part in narrowing conversions anyhow, cf. [dcl.init.list].
[ChangeLog][QtCore][QObject] The detection of narrowing conversions
when calling QObject::connect() when
QT_NO_NARROWING_CONVERSIONS_IN_CONNECT now takes also
into account user-defined implicit conversions that undergo
through a narrowing conversion.

Following wg21.link/LWG3228, it was found that a proper variant fix
requires that T* -> bool conversions be treated as narrowing
conversions in subclause wg21.link/dcl.init.lst. wg21.link/P1957R2 was
accepted in Prague 2020 as a DR and retroactively applies to older C++
standards.
Since we hard-code the algorithm of [dcl.init.lst], we can and must
add this manually.
[ChangeLog][QtCore][QObject] For the purposes of
QT_NO_NARROWING_CONVERSIONS_IN_CONNECT, pointer
(incl. pointer-to-member) to bool conversions are now considered
narrowing. This matches the resolution of a defect report in C++

CMake doesn't support removing subdirectories therefore one need to
convert all removal to conditional adds. The resulting code doesn't
win a beauty contest. That is because handle_subdir works on already
processed strings which means it doesn't have access to the boolean
operations. As such it can not minimize the expressions, but it works
and in the most simple cases it is pretty good.
The patch re-generates CMakeLists.txt under tests/auto/corelib/kernel
excluding qcoreapplication, qmetatype, qmimedata, qobject, qtimer,
which are suffering from unrelated problems, like for example Gui,
pthread linkage issues.

The bitmap cache for the first 64 signals being connected was only set when the
connection is added. It was never unset when the connection was removed.
Internal use of the connectedSignals bitmap is not hurt by it occasionally
saying a signal is connected even though it is not, since the purpose of those
checks is avoiding expensive operations that are not necessary if nothing is
connected to the signal.
However, the public API using this cache meant that it also never spotted
signals being disconnected. This was not documented. Fix the behavior by only
using the cache if it is up to date. If it is not, use a slower path that gives
the correct answer.
To avoid making disconnections and QObject destructions slower, the cache is
only updated to unset disconnected signals when new signal connections are
added. No extra work is done in the common case where signals are only
removed in the end of the QObject's lifetime.

The previous approach of having the signalbug helper in a subdirectory did
not work for shadow builds, as QFINDTESTDATA would not find that dir. By
putting both test and helper into the same directory, the helper will be
found in the test's current working directory.
The second problem was that not putting executables into debug/release
subdirectories might have lead to the WinRT AppxManifest being overwritten
by the wrong configuration. When Qt is configured with -release for
example, it was possible that the debug manifest (Manifest files are
always created next to the target) is written last and thus contains
debug VCLibs as a dependency.
