[mutter] clutter/stage-view: Add name property

[verdre <jonasd src gnome org>]

commit 6db94a0b7744cee0d1fb232a3697a8aa651f2b2c

    clutter/stage-view: Add name property
    
    Will be used for logging to identify what view a log entry concerns. For
    the native and nested backend this is the name of the output the CRTC is
    assigned to drive; for X11 it's just "X11 screen", and for the legacy
    "X11 screen" emulation mode of the nested backend it's called "legacy
    nested".
