gfx::Color is currently misused in many places. The DrawTargets expect
the color space to be in device space, e.g. what we are actually going
to draw using. Everything sitting above generally deals with sRGB, as
specified in CSS. Sometimes we missed the conversion from sRGB to device
space when issuing draw calls, and similarly sometimes we converted the
color to device space twice.
This patch splits the type in two. sRGBColor and DeviceColor now
represent sRGB and device color spaces respectively. DrawTarget only
accepts DeviceColor, and one can get a DeviceColor from an sRGBColor via
the ToDeviceColor helper API. The reftests now pass with color
management enabled for everything (e.g. CSS) instead of just tagged
raster images.
There will be a follow up patch to enable color management everywhere by
default on all supported platforms.

This removes a lot of old cruft in thebes to instantiate Cairo scaled fonts.
Instead, we only instantiate the Cairo scaled font inside Moz2D when we actually
need it for DrawTargetCairo. This thus gets rid of the duplicated code we had
inside both Moz2D and thebes to deal with Cairo scaled fonts.

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.

gfxPrefs Live preferences are almost identical to StaticPrefs.
We leave aside for now those that set a custom change callback as this feature isn't yet supported in StaticPrefs.

While we're here, fix the measurement of ' ' and 'x' so that we don't
measure the .notdef glyph if those glyphs aren't present.

With bug 1509358 having landed we don't need a draw target in a bunch of
places. This removes it from those places.

Add a pref called gfx.font_ahem_antialias_none which disables
antialiasing for any font with the family name "Ahem". This is useful
for wpt reftests where antialaising of Ahem causes spurious failures.

This rearranges how synthetic-bold use is determined in the font selection
& rendering code. Previously, we would decide during the font-selection
algorithm whether we need to apply synthetic-bold to the chosen face, and
then pass that decision through the fontgroup (storing it in the FamilyFace
entries of the mFonts array there) down to the actual rendering code that
instantiates fonts from the faces (font entries) we've selected.
That became a problem for variation fonts because in the case of a user
font, we may not have downloaded the resource yet, so we just have a "user
font container" entry, which carries the descriptors from the @font-face
rule and will fetch the actual resource when needed. But in the case of a
@font-face rule without a weight descriptor, we don't actually know at
font-selection time whether the face will support "true" bold (via a
variation axis) or not, so we can't reliably make the right decision about
applying synthetic bold.
So we now defer that decision until we actually instantiate a platform font
object to shape/measure/draw text. At that point, we have the requested
style and we also have the real font resource, so we can easily determine
whether fake-bold is required.
(This patch should not result in any visible behavior change; that will
come in a second patch now that the architecture supports it.)
