Extract Method msgType2i18nString() and use it to build 'rich' in a
single QStringBuilder expression.

Replace the switch over QtMsgType with an array of QT_TRANSLATE_NOOP'ed
strings. That introduces a dependency on the order and amount of enum
values, so add static and dynamic asserts to catch any change.

Saves memory allocations, as well as nearly 300B in text size on GCC 7
optimized Linux AMD64 builds.

This change made QMetaType start reporting that QJson* classes were

Since commit bf2160e7

, we can rely on
charNN_t support in all compilers except MSVC 2013, and since that
commit, we use (in 5.10, not 5.9, yet)

  !defined(Q_OS_WIN) || defined(Q_COMPILER_UNICODE_STRINGS)

when we only need charNN_t, the type, as opposed to its library
support (u16string, char_traits<char16_t>, ...).

This patch splits the Q_C_UNICODE_STRINGS macro into two, adding
Q_STDLIB_UNICODE_STRINGS for when we need std::uNNstring, leaving
Q_C_UNICODE_STRINGS for when we need just charNN_t support.

In QDebug, when constructing a QChar out of a char16_t, cast to ushort
first, since QChar(char16_t) was only officially introduced in Qt 5.10.

[ChangeLog][Potentially Source-Incompatible Changes] The internal
Q_COMPILER_UNICODE_STRINGS macro is now defined if the compiler
supports charNN_t, even if the standard library does not. To check for
availability of std::uNNstring, use the new Q_STDLIB_UNICODE_STRINGS
macro.

Creating a precompiled header exclusively for a one- or two-file module
is wasteful. The time that it takes to build the precompiled source is
on the same order as a regular compilation, so enabling precompiled
headers for those modules just makes the build slower.

Also make it possible to override the precompiled header by just setting
PRECOMPILED_HEADER to empty.

We can't just static_cast a child to QLayout, because the child might
not be a QLayout, and even if it was, we might be called from the
QObject destructor so we would not be a layout anymore.
Instead we can just qobject_cast the deleted object to a QLayout and
remove it from the layout with removeItem.
This would not take in account the case where we would be called because
the QLayout gets destroyed, so we handle this case from ~QLayout by
removing ourself from the parent.

Note that the comment in ~QLayout was wrong, as the layout gets destroyed
explicitly from ~QWidget, not from ~QObject.
