Returns true if configuration of viewfinder \a parameter is supported by camera backend.

/*!
\fn QCameraViewfinderSettingsControl::setViewfinderParameter(ViewfinderParameter parameter, const QVariant &value)
Set the prefferred \a value of viewfinder \a parameter.
Calling this while the camera is active may result in the camera being
stopped and reloaded. If video recording is in progress, this call may be ignored.
If an unsupported parameter is specified the camera may fail to load,
or the setting may be ignored.
Viewfinder parameters may also depend on other camera settings,
especially in video capture mode. If camera configuration conflicts
with viewfinder settings, the camara configuration is usually preferred.
