DomItem: use non-throwing variant access in ownerAs_impl()

Coverity was (incorrectly) claiming that ownerAs() would throw
bad_variant_access, due to the use of get<>(). But all uses of get<>()
are guarded by a matching if (holds_alternative<>), so this could not
have thrown, not even in the valueless_by_exception() case.

Still, get_if() is the preferred solution, since it checks once and
DRYs the code (names the type only once), so use that. From
experience, this will also shut up Coverity.

Amends 52d61e705ee606f3b673c757bdf253bdf6134a3b (6.2).

QmlPreview: Compress timestamps of replayed events

We don't want to wait as long as it took to record the events when
replaying them.

QtQml: Restore pre-6.12 handling of wrapped QObjects as return values

We need to unwrap them from QVariant. In addition, if we receive a
return value of a type that's explicitly a PointerToQObject but at the
same time NeedsDestruction, we need to respect both.

QmlDebug: Add a reusable interactive console

Factor the interactive command-line mechanism that was open-coded in
qmlprofiler into QmlDebugPrivate so that other QML debugging tools can
reuse it.

We move qmlprofiler's console handling into QmlDebug: QQmlDebugConsole
owns a QQmlDebugCommandListener on a worker thread, dispatches lines to
registered command handlers, renders a generated help listing and offers
a reusable yes/no confirmation flow. The listener keeps a single
persistent QTextStream and reports end-of-input so consumers can quit
when standard input is closed.

qmlpreview: Add interactive mode and --output option

This is modeled after the interactive mode that qmlprofiler already
offers. You can store the event stream into a .qtd file, and replay it.
In contrast to qmlprofiler, you can also kill and re-start the
application. That is handy if you notice the preview couldn't handle
some change and want to replay the stored input events into a clean
slate.

StyleKit: Fix oversized submenu arrow in MenuItem

fillHeight is true by default, so the arrow was stretching to fill
the available height and ended up larger than intended. The check
didn’t show this issue due to its image shape.

Set fillHeight: false for the submenu arrow so it uses its defined
height.
