fix sweep step for tainted QObject JavaScript wrappers

Origin: upstream, https://code.qt.io/cgit/qt/qtdeclarative.git/commit/?id=e6b2f88d892dcf39
Last-Update: 2022-02-13

Currently, whenever the garbage collector runs, it will destroy all
valid tainted wrappers.

Only null or undefined wrappers will be preserved in the
m_multiplyWrappedQObjects map.

It seems like "!" was overlooked in
3b5d37ce3841c4bfdf1c629d33f0e33b881b47fb. Prior to that change, it
was "!it.value()->markBit()", so calling erase() in the then branch
did make sense. But with "!it.value().isNullOrUndefined()", erase()
will be called for every valid wrapper, which is the opposite what we
want.

fix QML property cache leaks of delegate items

Origin: upstream, https://code.qt.io/cgit/qt/qtdeclarative.git/commit/?id=b2862e2bd84d651c
Last-Update: 2021-01-26

The delegate items are destroyed through an event loop by a call to a
deleteLater(). This, however, doesn't work when the application is
in the process of exiting and the event loop is already closed (i.e.
we're in a stack unwinding part that starts after app.exec()).

Combat this situation by setting a parent of the to-be-deleted object
to some QObject that will be destroyed e.g. QCoreApplication::instance()
before the program finishes. As QObjects clean their children on
destruction, this will make sure that we cleanup the previously leaking
thing regardless of the event loop.

The qmltime should be a tool, not a normal executable or an app.
