Note: This removes from the public API. The two most commonly
checked values from gammaNamed can still be tested with
gammaCloseToSRGB and gammaIsLinear.
Others can be tested for (exact or approximate) equality by
calling isNumericalTransferFn, and testing the resulting
skcms_TransferFunction in any method the client wants.

Moved named common transfer functions and gamuts to constexpr values in
SkColorSpace.h, in SkNamedTransferFn and SkNamedGamut namespaces.
Converted nearly all SkColorSpace::MakeRGB calls within Skia to use the
new factory with the named values. Multiple clients want a way to
extract named transfer function and gamut - this still doesn't provide
that, but this may be a better path forward for honestly advertising how
SkColorSpace works internally.

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.

This object is now redundant with fEncodedInfo. It holds an
SkColorSpace, which is never used now that SkCodec uses skcms.
SkCodec::getInfo() no longer returns a reference, but creates an
SkImageInfo from the SkEncodedInfo the same way fSrcInfo was
previously created.
Add SkCodec::bounds() and ::dimensions() to replace calling these
methods on getInfo().
Remove srcInfo from SkMaskSwizzler::Create, which just wants to know
whether the src is opaque.
Remove the srcColorType from conversionSupported. Only the base class
version used it. Make it look at fEncodedInfo.color() instead.

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.
