Replace all the old modes with two that should draw the same:
1) decode to the codec's "native" SkImageInfo, draw to dst;
2) decode to the dst's ct/at/cs, draw to dst.
Testing against --config srgb, p3, rec2020, narrow ought to give
us the kind of destination variety we were getting from the old
modes, and --configs 8888 shows off managed vs. unmanged color.
The only difference between the two is that 1) does any conversion at
draw time, 2) at decode time.
I don't quite understand why codec won't decode to some images to 565,
nor any images to 4444.

For now this is distinct from kRGBA_F16_SkColorType but treated the
same. Next steps are to see if we can keep it clamped to [0,1].
Switched a few switches away from default to exhaustive.
Took away any explicit SW clamps for now except the one we definitely
want in append_gamut_clamp_if_normalized().
Skip F16Norm in the DDL test because we can't yet distinguish it from
F16.

If we want to compare CSXform vs. tagged drawing, we should be able to
compare gbr-8888 vs. esgbr.
The spin happens when dump_png() converts to Rec.2020. This has the
"problem" that Gold and other naive image diff tools will think these
images are bytewise very different but once you look at them they'll
make sense to compare.
(You'd want to ideally diff esgbr with gbr-esrgb, but that config
asserts because it's SkColorSpaceXformCanvas doesn't like transforming
into tagged targets.)
(Yes, I chose "esgbr" to both make sense when you think about it but
also, more importantly, to be completely confusing.)

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.

- Encoders and decoders always assume kIgnore.
- They are less opinionated about F16 and color space,
we just trust the color space that's passed in, and
put that directly in the image (no sRGB encoding).
- SkBitmap and SkPixmap read/write pixels functions were
defaulting to kResepct, those are now always kIgnore.
- Many other bits of plumbing are simplified, and I
added a default of kIgnore to SkImage::makeColorSpace,
so we can phase out that argument entirely.
- Still need to add defaults to other public APIs that
take SkTransferFunctionBehavior.
- This makes gold think that we've dramatically changed
the contents of all F16 images, but that's because
it doesn't understand the (now linear) color space
that's embedded. Once we triage them all once, they
will work fine (and they'll look perfect in the browser).

565 and moving F16 to GCE-only (i.e. fast, abundant machines).
Similarly, remove "adobe" VIA that doesn't use Adobe RGB correctly...

Most of this is (obviously) not necessary to do, but once
I started, I figured I'd just get it all. Tools (nanobench,
DM, skiaserve), all GMs, benches, and unit tests, plus support
code (command line parsing and config stuff).
This is almost entirely mechanical.

We're not going to need the bit.
I've rewritten "esrgb" and "srgbnl" to express themselves the way I'd
like them to work. Their images are supressed in Gold already.

Code:
- Add a non-linear blending bit and makeNonlinearBlending()
to SkColorSpace
- remove enough F16=linear checks to make it possible to
create surfaces and encode pngs with nonlinear F16
Testing:
- add "esrgb" software config to DM, run it
- add "srgbnl" software config, run it
- deemphasize importance of "srgb" config on bots
- update unit tests to reflect relaxed F16 constraints
- add a new unit test file with _really_ basic tests,
and a new unit test that's not working yet
