Converted the #define variable NS_STYLE_FLEX_DIRECTION to an enum class in nsStyleConsts.h and made changes in other files that access it

I want to do this so that I can get rid of Either<>. The reasons for getting rid
of either are multiple:
* It doesn't generate as nice C++ code using cbindgen.
* It isn't that nice to use either from Rust.
* cbindgen has bugs with zero-sized types.
I started using this for ColorOrAuto and a few others, for now.

-moz-tab-size, border-image-outset and border-image-slice.
This is not a particularly interesting patch, just removes some code. We can
remove way more code when a few related properties are also ported.

It's a global object, it doesn't have to be stored in nsFont. Pass it from the
caller like the user font set and co.
Depends on D20141

This is more consistent with what the Rust bits of the style system do, and
removes a pointer from ComputedStyle which is always nice.
This also aligns the Rust bits with the C++ bits re. not treating xul pseudos as
anonymous boxes. See the comment in nsTreeStyleCache.cpp regarding those.
Can't wait for XUL trees to die.

The reason why we use RelaxedAtomBool is that
ScrollSnapUtils::GetSnapPointForDestination() is called both from the main and
the compositor threads, and the function will have a branch depending on the
pref value.

We already avoid putting styles in the shared style cache for an element that
has animations[1] but if we are doing the initial style of two siblings where
the _second_ has animations applied, there is nothing to stop us from trying to
share with the first (un-animated) element. This patch adds a check to prevent
sharing in that case since sharing style between animated elements is unsound
for the reasons described in [1].
A number of tests including:
testing/web-platform/tests/web-animations/animation-model/animation-types/visibility.html
will fail without this fix once we remove the style flush from
KeyframeEffect::SetKeyframes later in this patch series.

Really sorry for the size of the patch :(
Only intentional behavior change is in the uses of HasLengthAndPercentage(),
where it's easier to do the right thing. The checks that used to check for
(IsCalcUnit() && CalcHasPercentage()) are wrong since bug 957915.

This patch:
* Makes LengthPercentageOrAuto generic, and removes a bunch of code fo
LengthPercentageOrNone, which was used only for servo and now can use the
normal MaxLength (with a cfg() guard for the ExtremumLength variant).
* Shrinks MaxLength / MozLength's repr(C) reperesentation by reducing enum
nesting. The shrinking is in preparation for using them from C++ too, though
that'd be a different bug.
* Moves NonNegative usage to the proper places so that stuff for them can be
derived.
I did this on top of bug 1523071 to prove both that it could be possible and
that stuff wasn't too messy. It got a bit messy, but just because of a bug I
had fixed in bindgen long time ago already, so this updates bindgen's patch
version to grab a fix instead of ugly workarounds :)

Also for the intersection observer root margin, since it was easier to fix it
up and clean it up than not doing it.
This is the first big step to get rid of nscoord. It duplicates a bit of logic
in nsLayoutUtils since for now max/min-width/height are still represented with
nsStyleCoord, but I think I prefer to land this incrementally.
I didn't add helpers for the physical accessors of the style rect sides that
nsStyleSides has (top/bottom/left/right) since I think we generally should
encourage the logical versions, but let me know if you want me to do that.

But enable it in all tests because a lot of them rely on using it in the
style="" attribute for example, or in inline stylesheets, which will no longer
parse this (even in chrome documents), and we don't want to rewrite all the XUL
and XBL tests.

Not the prettiest, but it will work, and LengthPercentage will be 12 bytes which
is pretty good (we could do better if wanted I guess):
* Au(i32) length;
* f32 percentage;
* AllowedNumericType(u8) clamping_mode;
* bool has_percentage;
* bool was_calc;
This will allow me to start moving C++ stuff to use this representation.

This patch implements -moz-gtk-csd-hide-titlebar-by-default media query
to check if the system titlebar should be disabled by default on Linux systems
(it's already disabled on Window/Mac).
It also removes explicit definition of browser.tabs.drawInTitlebar preference on Linux.
When browser.tabs.drawInTitlebar is missing the -moz-gtk-csd-hide-titlebar-by-default
is used to obtain the titlebar state. When browser.tabs.drawInTitlebar is set
in about:config or by Customize menu, the user peference is used instead of the default.
It also fixes a -moz-gtk-csd-available media query,
it was always true regardless the actual system setting.
