wl_egl_window size must exactly march GL rendering pipeline setting.
Compositor and widget can have different window sizes during window resize when widget
is resized faster than layout can render. Firefox window is rendered misplaced then
and it's "jumping" as layout size is behind toolkit size.

CompositingRenderTargetOGL objects are no longer reused between frames. They are
recreated each frame around a reused framebuffer. This lets us remove the
SetOrigin method again, because we specify the right render target origin on
creation.

This makes profiler screenshots and frame recording work again, when native
layers are used. The copying is a bit unfortunate. Maybe we can combine this
copy with the first downscaling step in the future. Or for frame recording,
which doesn't use downscaling, we could readback the layers individually and
reassemble them in CPU memory. But both of those solutions are more complex
than this.

The call to TransformAndClipBounds already clips destRect to renderBounds.
However, if the resulting rect was empty, the Inflate call would make it
non-empty again. And now the decision whether we would cull would depend on the
rect's position: Sometimes TransformAndClipBounds would place the empty rect at
a position along an edge of renderBounds, and then the inflated-from-nothingness
2x2 rect would overlap renderBounds and we wouldn't cull.

There are three circumstances that make these transformations equivalent:
- aClipRectIn and aClipRectOut are never both non-null.
- The value of *aClipRectOut is ignored if *aRenderBoundsOut is empty.
- aRenderBounds.TopLeft() is always (0, 0) because the ClientLayerManager
calls targetBounds.MoveTo(0, 0) on the rect that eventually becomes
aRenderBounds.

On platforms that don't use native layers for rendering, we usually want reftests
to see exactly what's going to end up in the window. It's conceivable that
rendering into offscreen framebuffers might miss bugs on those platforms (though
I'm not sure if we've seen any evidence of this).
But when we're rendering to native layers, we have non-default framebuffers either
way, so we might as well create our own framebuffer rather than asking a native
layer for one. We're not interested in getting this rendering to the screen, so
it's better to leave the native layer out of this.

This makes CompositorOGL always render into offscreen render targets.
CompositorOGL no longer expects the GLContext to have a default framebuffer.
This duplicates a bunch of code from GLContextCGL, but that code can be removed
from GLContextCGL once WebRender no longer needs it.
This also makes it so that we don't recreate render targets on every frame;
instead, we create one render target for every IOSurface in the native layer's
"swap chain" and cycle through those render targets. We only throw away the
render targets when the window is resized or closed.

It looks like a big patch but it's mostly just moved code, with some duplication:
- Layer creation and destruction moves to LayerManagerComposite and RendererOGL.
- BasicCompositor IOSurface setup code moves to BasicCompositor.cpp.
- OpenGL IOSurface setup code moves to CompositorOGL and RenderCompositorOGL.
The duplication is a bit unfortunate but the LayerManagerComposite code will
diverge from the WebRender code soon.
BeginFrame gets a new argument aNativeLayer. This argument will go away again
over the course of this patch queue. But for now, BeginFrame is the best place
to do the layer setup because it's a very close place to PreRender which is
where that code was previously.
I wasn't able to think of a nice way to give CompositorOGL and BasicCompositor
platform-specific behavior without #ifdefs. So now LayerManagerComposite uses
the "cross-platform" NativeLayer interface, but CompositorOGL and
BasicCompositor use NativeLayerCA because they actually need the IOSurface, and
they do that in #ifdef'd code.
Luckily, NativeLayerCA.h can be included in both .cpp files and in .mm files.

There's no other caller that sets ReadBuffer to anything else, and GL_BACK is

This removes the assumption that there is a default framebuffer to read from,
in order to prepare for a world in which all rendering goes into non-default
framebuffers.
The current render target's framebuffer is already bound when this function is
called.

This requires replacing inclusions of it with inclusions of more specific prefs
files.
The exception is that StaticPrefsAll.h, which is equivalent to StaticPrefs.h,
and is used in `Codegen.py` because doing something smarter is tricky and
suitable for a follow-up. As a result, any change to StaticPrefList.yaml will
still trigger recompilation of all the generated DOM bindings files, but that's
still a big improvement over trigger recompilation of every file that uses
static prefs.
Most of the changes in this commit are very boring. The only changes that are
not boring are modules/libpref/*, Codegen.py, and ServoBindings.toml.

Currently it's completely unclear at use sites that the getters for `once`
static prefs return the pref value from startup, rather than the current pref
value. (Bugs have been caused by this.) This commit improves things by changing
the getter name to make it clear that the pref value obtained is from startup.
This required changing things within libpref so it distinguishes between the
"base id" (`foo_bar`) and the "full id" (`foo_bar` or
`foo_bar_DoNotUseDirectly` or `foo_bar_AtStartup` or
`foo_bar_AtStartup_DoNotUseDirectly`; the name used depends on the `mirror` and
`do_not_use_directly` values in the YAML definition.) The "full id" is used in
most places, while the "base id" is used for the `GetPrefName_*` and
`GetPrefDefault_*` functions.
(This is a nice demonstration of the benefits of the YAML file, BTW. Making
this change with the old code would have involved adding an entry to every
single pref in StaticPrefList.h.)
The patch also rejigs the comment at the top of StaticPrefList.yaml, to clarify
some things.

Without CoreAnimation, back-pressure was applied by SwapBuffers: On a
double-buffered NSOpenGLContext which is bound to an NSView, [context flushBuffer]
waits for the previous frame to be finished. With CoreAnimation, the context
is no longer bound to an NSView, and SwapBuffers acts as a regular glFlush.
glFlush on its own does not prevent overproduction.
If we submit GPU work at a faster rate than the GPU can handle, we end up
delaying the window server's GPU work. This can cause the window server to skip
frames. So even if Gecko can produce frames at 60FPS, the window server might
only present those frames at 30FPS, skipping every second frame.
