Extracts out the creation of an NSEvent from a WidgetKeyEvent in
TextInputHandler.mm into generic helper method. The helper is used by headless
to create a fake NSEvent to then build edit commands from key events.

Many tests rely on the minimum size of widgets to
be set. Also, the precise size seems to matter for some
tests that have hard coded offsets.

This better emulates a window manager and triggers the
required activated/deactivated events on the proper windows as
they are closed or hidden.

To make the HeadlessCompositorWidget work under Windows as well as Linux, I had
to change the way that I hooked it into the existing CompositorWidget system.
Under GTK, the CompositorWidgetInitData and CompositorWidgetDelegate types
provided the information needed by the headless compositor widget already (the
widget client size). On Windows, however, the definitions of these types
differ, and the client size information is simply retrieved from the platform
APIs when needed.
After this patch, CompositorWidgetDelegate is renamed to
PlatformCompositorWidgetDelegate, and a new base class called
CompositorWidgetDelegate is added with "AsPlatformSpecificDelegate()" and
"AsHeadlessCompositorWidget()" methods. In non-headless mode, widgets use
AsPlatformSpecificDelegate() to access the Windows- and GTK-specific delegate
APIs. In headless mode, AsHeadlessCompositorWidget() is used to access the
singular CompositorWidget implementation for headless. Meanwhile, the
CompositorWidgetInitData IPDL type is made into a union which always contains a
headless-specific HeadlessCompositorWidgetInitData struct and under GTK and
Windows also contains an {X11,Win}CompositorWidgetInitData struct.
This also includes a small patch to ensure that the GPU process and
hardware-accelerated compositing are always disabled under headless mode. These
features weren't activated by default in the Linux environments I tested in, but
did end up activating (and then promptly crashing Firefox) when I tested on
Windows.

It seems that my reworking of how the z-index events are sent in the patch
pertaining to active window tracking made it so that we can have headless
widgets default to being invisible again, which matches the behavior on all
other platforms. This then allows us to avoid applying size mode change side
effects while a window/widget is invisible, matching the behavior on Windows and
allowing the relevant web platform tests to pass despite the low screen
resolution with which we run Windows VMs in testing (eg.
open-features-non-integer-height.html).

This fixes a series of issues uncovered by the Web Platform Tests.
The most immediately noticeable symptom was that, during shutdown, PuppetWidgets
on the client side attempted to delete shadow layers that were never created on
the compositor side. The usage of BasicLayerManager in all other widgets due to
headless mode meant that the PLayerTransactionParent was never initialized with
a layer manager, and thus discarded all transaction messages it received but not
delete layer messages.
The effects of only using BasicLayerManager in headless mode also showed up in
the web platform reftests, which ended up as blank white boxes in e10s mode as
the compositor thread never received paint instructions. Switching over to
using ClientLayerManager in headless mode causes these paint instructions to be
relayed.
In order to make ClientLayerManager work under headless mode, it was necessary
to implement a HeadlessCompositorWidget and hook that up to the CompositorWidget
creation function in widget/gtk. A follow-up patch will be necessary to hook up
the same for the other supported widget platforms.

Every other widget backend ensures widget size is bounded to screen size, but
this check was missing from headless.

Defining the default draw target avoids the previous mix of cairo
and d2d layers, which would trigger an assertion when capturing
a page with the widget layers.
Full Firefox on Linux can now be run with a --headless flag.
This includes seven parts:
1) Running all marionette tests in headless mode.
2) Prevents crashes where Firefox calls into GTK.
3) Adds a headless screen helper which supports changing the headless
screen size with the environment variables MOZ_HEADLESS_WIDTH and
MOZ_HEADLESS_HEIGHT.
4) Supports simulating moving a headless window.
5) Adds a stubbed out nsSound implementation.
6) Supports simulating size mode changes of headless windows.
7) Adds the --headless flag for Firefox.
Supports creating a windowless browser on Linux without an X server. Most of the
changes are just adding branches to avoid calls in to GTK which calls
into X. Some of the bigger additions were adding a separate headless widget
which implements just enough to render a page. A headless look and
feel were also added since there are many calls into GTK in the platform
specific one.
