AE allows for optional cycling of evolution, after a certain number of

To support:
- split off the base/offset component into a separate uniform
(currently front-loaded into evolution)
- introduce an additional "cycle" (period) uniform to mod() the noise
plane calculations

`a || b` only evaluates b if a is false. `a | b` always evaluates
both a and b. If a and b are of type bool, `||` is usually what you
want, so clang now warns on `|` where both arguments are of type bool.
In Skia, 3 of 3 uses of `|` were intentional as far as I can tell (one
had an explicit comment, the other two didn't). Rewrite them slightly
to make this intent more clear and to suppress the warning.
There was also one use of `&`. That one looks like a (benign) typo for
`&&`, so change it.

Classes of issues addressed:
1. static constexpr class variables aren't automatically inline. Already handled in a separate CL
2. Lack of C++17 copy elision means classes of objects constructed at function return need a copy or move constructor even if RVO will mean it isn't called.
3. Nested braced init no longer allowed for base classes of subclasses without constructors.
4. template static constexpr var in template class throws error about redundant initialization. Adding inline and removing defn outside of class fixes it.
5. Some places that should have been including std headers now actually need to include them.
6. No auto template parameters.
7. No lambdas in constexpr funcs.

This is in prep for compiling with -std=c++14 and -Wno-c++17-extensions
when building with clang. Chrome has encountered problems with
third_party headers that are included both in Skia and other Chrome
sources that produce different code based on whether preprocessor macros
indicate a C++14 or C++17 compilation.
In C++17 they are already inline implicitly. When compiling with C++14
we can get linker errors unless they're explicitly inlined or defined
outside the class. With -Wno-c++17-extensions we can explicitly inline
them in the C++14 build because the warning that would be generated
about using a C++17 language extension is suppressed.
We cannot do this in public headers because we support compiling with
C++14 without suppressing the C++17 language extension warnings.

In addition to single line (point) text, AE also supports path layout
for paragraph text.
At a high level, the paragraph box top is mapped to the path (following
alignment rules), and each glyph is displaced along its path positioning
vector, post orientation.
The main difference compared to point text, is that the distance on path
is based on the fragment position relative to the paragraph left edge.
The paragraph box also plays a role in alignment: left/center/right
aligns with path start/mid/end.
This includes a tangential optimization: instead of validating cached
contour data in each PathInfo::getMatrix() call, we only check once at
a higher level (onSync) -- to avoid performing a shape vector comparison
for each fragment.

The Fill effect has separate "color" and "opacity" components.
In AE, the color chooser does not allow modifying the alpha channel --
the only source for Fill transparency is the opacity property.
Thus, the alpha component of the color property should always be 1.
But in practice, it appears Bodymovin sometimes exports the color with a
zero alpha field (BM always encodes colors as 4-float arrays).
To workaround this issue, update Fill to ignore the color alpha and only
use the explicit opacity.

Turns out AE's saturation is more sophisticated, both in implementation
and in control mapping.
Updating the effect to use a chain of specialized color filters:
- keep HSLAMatrix() for hue adjustments
- introduce a custom runtime effect for saturation
(following AE's semantics)
- use a plain Matrix() CF for lightness adjustments
