Document Qt.openUrlExternally behaviour and associated risk

We call out QDesktopServices being used, in case we at some point add
a allow/deny list on that level.
We also ignore the case where it is not used and we simply return false
because QtQuick was not imported, as that adds mostly confusion.

Fixes: QTBUG-148277

QQmlAnyBinding::installOn: Fix IgnoreInterceptors with dynamic metaobjects

If installOn was called on an object with an alias to a BINDABLE
property (e.g. via PropertyChanges), we would fail to resolve the
UntypedBindable. The reason is that we were attempting a direct call of
the static meta-objects function (via qt_metacall). This certainly
bypasses interceptors, but it also bypasses the QQmlVMEMetaObject logic
which resolves aliases.

After resolution, we now always use QMetaObject::metacall, but set a
flag on any potential interceptor meta-object. We need to set that flag
recursively on the meta-object parent chain, as we can't know where
the relevant interceptor sits in the parent chain.
We have to resolve any aliases first, as we'd otherwise set the flag on
the wrong dynamic meta-object if the alias points to another object.

Alternatively, we could modify the metacall for BINDABLE to also pass an
(optional) flags argument, but that change requires larger coordination
between qtbase and declarative, and should at least not be backported.
