This implements the new 'bounds' event that is part of the xdg_toplevel
interface in the xdg-shell protocol. It aims to let clients create
"good" default window sizes that depends on e.g. the resolution of the
monitor the window will be mapped on, whether there are panels taking up
space, and things like that.

Change to use the headless backend with a virtual monitor, instead of
the nested backend. This means tests can create and use virtual input
devices, which isn't possible with the nested backend.

A client can create a token without any seat, serial, or surface. In
this case, we'd still try to grab, which would run into some unforseen
code paths, potentially resulting in the following crash:

Fix this by not trying to grab if not enough parameters was passed when
creating the token. Also add a test case that reproduces the above
crash.

and the subsurface was not previously detached from it using
`wl_subsurface_destroy()`.
Without 'window-actor/wayland: Remove subsurface actors on dispose' this
test would fail.

Without 'wayland/surface-actor: Reset and sync subsurface state when
resetting' this test would fail.
This also adds a simple framework for testing lower level Wayland
semantics.
In contrast to the test-client and test-driver framework, which uses
gtk and tests mostly window management related things, this framework is
aimed to run Wayland clients made to test a particular protocol flow,
thus will likely consist of manual lower level Wayland mechanics.
A private protocol is added in order to help out clients do things they
cannot do by themself. The protocol currently only consists of a request
meant to be used for getting a callback when the actor of a given
surface is eventually destroyed. This is different from the wl_surface
being destroyed due to window destroy animations taking an arbitrary
amount of time. It'll be used by the first test added in the next
commit.
