This is mostly a simple lexical search+replace but the absence of operator< for
std::weak_ptr<T> leads to some complications, particularly with Evoral::Sequence
and ExportPortChannel.
macOS has its own z-axis stacking (see Manager::set_transient_for) for
dialog and utility windows of a single application. There only case to
set a dedicated transient parent is to keep the child window on top of a
dialog.
Valid use-cases are e.g.
Plugin Preset Name entry on top of a PluginWindow
Export Format Settings on top of the Export Dialog
Alternatively one would need to patch gtk to handle
[NSView shouldDelayWindowOrderingForEvent] and explicitly reorder
siblings of a common parent window.
This fixes an issue that plugin windows cannot be re-stacked but were
previously always stacked in the order they were opened.
