This patch enables EGL robustness with WebRender. It also tries harder
to get RBAB, favouring KHR+RBAB over EXT-RBAB, as testing with Intel and
NVIDIA Mesa drivers on Ubuntu suggests we can get KHR+RBAB but not
EXT+RBAB. It also adds support for requesting NVIDIA specific resets via
EGL_NV_robustness_video_memory_purge.

Not all configurations have both libGL and libGLES present, and this
matches the order which glxtest loads them. Without this, a user might
pass glxtest, which says they can use EGL, but then not have libGLES on
the library path.

KHR_partial_update allows us to avoid rerendering the entire
backbuffer every frame, and instead only render what has changed on
the current frame, as well as the difference between the current
backbuffer and the current frontbuffer. It works similarily to
EXT_buffer_age, which we already support, with the additional
requirement that we must call eglSetDamageRegion each frame before
rendering to the backbuffer.
Modify GLContextEGL::GetBufferAge() so that it queries the age if
either EXT_buffer_age or KHR_partial_update are available. This will
now automatically be queried by webrender through the
PartialPresentCompositor trait. Add a new function to that trait,
set_buffer_damage_region(), whose RenderCompositorEGL implementation
calls eglSetDamageRegion(). Call this from composite_simple(), once
the damage rect has been calculated but before rendering to the
backbuffer.
Additionally, change both RenderCompositorEGL and
RenderCompositorOGL's implementations of
ShouldDrawPreviousPartialPresentRegions() to unconditionally return
true, rather than checking for the existence of EXT_buffer_age (or
adding a new check for KHR_partial_update). The lack of these
extensions does not mean that webrender is able to skip rendering
previous frames' damage. Rather the opposite, it means we cannot
render *only* the previous frames' damage, and must instead always
render the entire buffer.

This is meant to save us in cases where the message loop in GPU process
receives commands related to resources that point to the old EGL context
that was just shut down. Since the symbols are erased, we'd end up with
trying to execute a nullptr on `MakeCurrent()`. With marking the context
as lost, however, no symbols will be accessed.

EGL with buffer-age requires the application to keep the front buffer
fully consistent. This means we have to draw the previous frame's
damage as well. (But we don't need to include it in the hint we're
sending to the system compositor via SwapBuffersWithDamage.)

EGL_KHR_swap_buffers_with_damage (or EGL_EXT_swap_buffers_with_damage)
is an EGL extension that allows the application to inform the display
server (system compositor) which areas of the window have changed.
This commit implements support for that extension in the layers compositor.
The layers compositor always renders the whole frame, so we're only getting
the benefit of not redrawing unchanged areas *in the system compositor*,
not actually doing partial invalidation/compositing,
but that makes the implementation simpler (no need to track buffer age).

EGL_ANGLE_experimental_present_path was enabled for fast rendering to SwapChain by ANGLE. But current gecko does not request ANGLE to render to SwapChain for WebRender. Then we do not need to use EGL_ANGLE_experimental_present_path anymore. But Its usage still has a side effect that y is flipped. But OS compositor implementation on Windows does not want it. And it seems not good to continue to use EGL_ANGLE_experimental_present_path since it is experimental feature.
But when EGL_ANGLE_experimental_present_path is removed, rendering result of frame buffer is y flipped with ANGLE compared to other OpenGL implementation. It needs to be handled in WR. It is similar to chromium.

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.
