I tried to follow exactly the same strategy as a start.
(Though I did fix the off-by-one dimensions.)
It does rather look like we only need 3D and 4D now
that I've looked at the call sites.
Looks like about a 20% speedup.

It looks like our recursive approach is faster than interp3D(),
and we'd prefer trilinear interpolation over tetrahedral for quality.

- Avoid calling floor() and ceil(), which are real
external calls on most platforms.
- Interpolate all output channels in parallel.
- Simplify recursion, allow the compiler to unroll.

This operation assumes 0-1 input and guarantees 0-1 output.
The old clamp was poorly written, causing the possibility
for NaNs to not be set to 0.

Changed ICC parsing/SkGammas/SkColorLookUpTable to handle non-3-channel
inputs. Parsed CMYK A2B ICC profiles. Integrated this with SkJpegCodec
(the only file that supports CMYK) and SkColorSpaceXform_A2B to allow
parsing and color xforming of ICC CMYK images.

This reverts commit 51c3fcd376c5c9972d9476b5532f6164375a38d1.
Reason for revert: ASAN, MSAN both take issue with parse_and_load_gamma()

(1) Fix subtle comparison bug so we interpolate the proper tetrahedral.
(2) Add new comments - the clamp is necessary.
(3) SkCSXformPrintf requires an extra friend class to compile.

Bug(?) in the tetrahedral interpolation causes output values to go out
of range a bit (1.035/1.0) in the upper range. We will just clamp for
now as a temporary fix.

There is support for all features of SkColorSpace_A2B.
Tests for these functionality were adapted from
the XYZ xform, plus a CLUT-specific test was added.
Shared functions used by both SkColorSpaceXform_XYZ and SkColorSpaceXform_A2B
have been moved into a shared header.
