Subject: [PATCH 1/4] perf-helper: Add content for custom drawing
Drawing windows got a lot more involved with the advent of client-side
decorations. Instead of accounting for visible and invisible borders,
titlebar and shadows when necessary, just add an empty child for the
custom drawing.

Those aren't used for anything, but make the helper dependent on X11.

Subject: [PATCH 3/4] perf-tool: Spawn perf-tool-helper from gnome-shell
On Wayland, the display server is the Wayland compositor, i.e.
`gnome-shell` itself.
As a result, we cannot spawn `gnome-shell-perf-helper` before
`gnome-shell` is started, as `gnome-shell-perf-helper` needs to connect
to the display server.
So, instead of spawning `gnome-shell-perf-helper` from the perf tool,
start it from `gnome-shell` itself.

Subject: [PATCH 4/4] perf-tool: Allow to run as a Wayland compositor
`gnome-shell-perf-tool` is initially designed to run on X11, using the
`--replace` option which does not work when gnome-shell is a Wayland
compositor.
A solution would be to run `gnome-shell-perf-tool` in place of just
`gnome-shell` to run the entire perf session under Wayland, but the
script `gnome-shell-perf-tool` does not spawn `gnome-shell` as a Wayladn
compositor, so that fails as well.
Add a `--wayland` option to `gnome-shell-perf-tool` so that it can
optionally spawn gnome-shell as a Wayland compositor so the whole perf
tool can be starred from a console with:
```
$ dbus-run-session -- gnome-shell-perf-tool --wayland
```
Alternatively, for testing purposes, it can also be started nested with:
```
$ dbus-run-session -- gnome-shell-perf-tool --nested
```
