It's been driving me nuts that I can't just write `SkMatrix44 m;`,
and I often don't care whether it's initialized or not. The default
identity constructor would be nice to use, but it's deprecated.
By tagging this constructor deprecated, we're only hurting ourselves;
our big clients disable warnings about deprecated routines and use it
freely.
A quick tally in Skia shows we mostly use the uninitialized constructor,
but sometimes the identity constructor, and there is a spread of all
three in Chromium. So I've left the two explicit calls available.
I switched a bunch of calls in Skia to use the less verbose constructor
where it was clear that it didn't matter if the matrix was initialized.
Literally zero of the kUninitialized constructor calls looked important
for performance, so the only place I've kept is its lone unit test.
A few places read clearer with an explicit "identity" to read.

Draws basically the same as f16.
The existing load_f32, load_f32_dst, and store_f32 stages all had the
same bug that we'd never noticed because dy was always 0 until now.

The type SkColorSpace_Base doesn't need to exist. Its one type() query
can be answered instead by toXYZD50().
Now all that's left in the file is SkGammas, so rename it to SkGammas.h.

Many tests and examples use drawText with
a guess of how long the text is in bytes,
or a call to strlen(). Add a helper to
SkCanvas to simplify these examples.
Add another helper for SkString.

gm.h includes sk_tool_utils.h but does not use it.
The bulk of this CL makes each gm that uses sk_tool_utils include it.
sk_tool_utils.h also provided SkRandom and SkTDArray,
so a couple GMs add those headers too.

Matches our naming convention for all other types - factories that
return sk_sp (or any type that intelligently manages its own
lifetime) are named Make.
Previous factories are still around, assuming
SK_SUPPORT_LEGACY_COLOR_SPACE_FACTORIES is defined. Enable that
define for Android, etc.

The refactoring breaks off A2B0 tag support into a separate
subclass of SkColorSpace_Base, while keeping the current
(besides CLUT) functionality in a XYZTRC subclass.
ICC profile loading is now aware of this and creates the A2B0
subclass when SkColorSpace::NewICC() is called on a profile
in need of the A2B0 functionality.
The LabPCSDemo GM loads a .icc profile containing a LAB PCS and
then runs a Lab->XYZ conversion on an image using it so we can
display it and test out the A2B0 SkColorSpace functionality,
sans a/b/m-curves, as well as the Lab->XYZ conversion code.

It will now reside in SkColorSpace_Base. Future work for SkColorSpace
will cause this function to not be desirable or sensible to call on
all SkColorSpaces. Call sites were changed to make a kSRGBLinear_Named
instead of kSRGB_Named -> makeLinearGamma() (the majority of cases),
and if that was not possible, SkColorSpace_Base::makeLinearGamma()
was called instead.

We were effectively storing the transpose, which made all of our
operations on individual colors, and our concatenation of matrices
awkward and backwards.
I'm planning to push this further into Ganesh, where I had incorrectly
adjusted to the previous layout, treating colors as row vectors in the
shaders.

After several different strategies, this one appears to work
well. The basic test:
1) For a variety of drawing techniques, we render fixed size
rectangles. (Solid colors via paint color, bitmap, etc...)
2) For each method in #1, we render to both an sRGB and
WideGamutRGB offscreen surface. (AdobeRGB isn't wide enough
to clearly demonstrate if things are working or not).
3) Use readPixels to fetch the raw (still in wide gamut) pixel
data, then draw that directly to the final canvas.
So, for each pair of squares, they should look clearly
different. Currently, with the GPU backend, only the bicubic
bitmap paths have that behavior. Adding more test cases (and
fixing the ones that are already incorrect) will be the long
tail of gamut transformation.
Current output (with my other patchset, which fixes all
bitmap draws): https://screenshot.googleplex.com/wsL3x7eCtWE.png
