Add support for scaled logical monitor framebuffers

Browse source 
This commit adds support for rendering onto enlarged per logical
monitor framebuffers, using the scaled clutter stage views, for HiDPI
enabled logical monitors.

This works by scaling the mode of the monitors in a logical monitors by
the scale, no longer relying on scaling the window actors and window
geometry for making windows have the correct size on HiDPI monitors.

It is disabled by default, as in automatically created configurations
will still use the old mode. This is partly because Xwayland clients
will not yet work good enough to make it feasible.

To enable, add the 'scale-monitor-framebuffer' keyword to the
org.gnome.mutter.experimental-features gsettings array.

It is still possible to specify the mode via the new D-Bus API, which
has been adapted.

The adaptations to the D-Bus API means the caller need to be aware of
how to position logical monitors on the stage grid. This depends on the
'layout-mode' property that is used (see the DisplayConfig D-Bus
documentation).

monitors in a logical pixel coordinate

@layout_mode current layout mode represents the way logical monitors
are layed out on the screen. Possible modes include:
1 : physical
2 : logical
With physical layout mode, each logical monitor has the same dimensions
an the monitor modes of the associated monitors assigned to it, no
matter what scale is in use.
With logical mode, the dimension of a logical monitor is the dimension
of the monitor mode, divided by the logical monitor scale.
Possible @properties are:
* "supports-mirroring" (b): FALSE if mirroring not supported; TRUE or not
present if mirroring is supported.
* "layout-mode" (u): Represents in what way logical monitors are laid
out on the screen. The layout mode can be either
of the ones listed below. Absence of this property
means the layout mode cannot be changed, and that
"logical" mode is assumed to be used.
* 1 : logical - the dimension of a logical monitor is derived from
the monitor modes associated with it, then scaled
using the logical monitor scale.
* 2 : physical - the dimension of a logical monitor is derived from
the monitor modes associated with it.
