Fix SW sRGB dst + LCD coverage bug.

We're using the linear procs for sRGB destintations
and the sRGB procs for linear destinations.  Fix that.

C.f. State32::getLCDProc(), which flags |= kDstIsSRGB_LCDFlag.
kDistIsSRGB is (1<<2) == 4, so the sRGB procs must be 4-7, not 0-3.

Cleanup of code that converts from GPU-backed resources to SkImageInfo

Functions like GrMakeInfoFromTexture encouraged incorrect code to be
written. Similarly, the ability to construct an info from any GrSurface
was never going to be correct. Luckily, the only client of that had all
of the correct parameters much higher on the stack (and dictated or
replaced most of the properties of the returned info anyway).

With this, I can finally remove the color space as an output of the
pixel config -> color type conversion, which was never going to be
correct.

Add clamp to sk_linear_to_srgb, reorder instructions

Improves performance for xforms toSRGB and to2Dot2.  Seems
more optimal to save clamping until the end.  That way we
don't stall the mul pipeline with a min/max.
toSRGB:  371us -> 346us
to2Dot2: 404us -> 387us

FWIW, it probably makes sense to clamp inside
sk_linear_to_srgb anyway.  If not, we should potentially
provide two versions (one that clamps and one that
doesn't).

limit the number of points in SkDashPathEffect::asPoints

If the length of a line path is sufficiently long relative to the dash
interval, it is possible to cause SkDashPathEffect::asPoints to produce
so many points that it overflows the amount that can fit in an int type,
or otherwise produce non-finite values, i.e. path from (0,0) to (0,9e15)
with a dash interval of 1.

This fixes that by capping the amount of points to a sane limit - in this
case, 1mil, since that limit is also used in utils/SkDashPath.cpp and has
precedent.

Correct sRGB <-> linear everywhere.

This trims the SkPM4fPriv methods down to just foolproof methods.
(Anything trying to build these itself is probably wrong.)

Things like Sk4f srgb_to_linear(Sk4f) can't really exist anymore,
at least not efficiently, so this refactor is somewhat more invasive
than you might think.  Generally this means things using to_4f() are
also making a misstep... that's gone too.

It also does not make sense to try to play games with linear floats
with 255 bias any more.  That hack can't work with real sRGB coding.

Rather than update them, I've removed a couple of L32 xfermode fast
paths.  I'd even rather drop it entirely...

Fix context creation problems in dm

Fixes these issues:

1. The glXCreateContextAttribsARB call seems to modify the
context_attrib parameter upon failure. Since context_attrib was static,
if it first tried to create an OpenGL 4.4 context and it failed, further
attempts to create a context with lower versions would also fail.

2. Getting an OpenGL 3.0 context was never tried.

3. Context creation for ES 3.0 was failing on my machine. Since ES 2.0
looks like the intended version from the surrounding code, I set it to
that. It could be rewritten to use a similar loop as standard OpenGL and
try from the highest version to the lowest.

GN: refactor third_party/gni

  This fixes the build on Linux (dep on third_party:zlib -> third_party/zlib).

  I've moved declare_args() {} back to each .gn file... seems like args want
  to be as local as possible in GN land.

  Additionally, refactor all the common third_party config and warning flag
  changes into a template, third_party.  This lets it all live together in a
  .gni: at head unwanted_configs can be in a .gni (it's just a variable) but
  config("no_warnings") (and thus third_party_configs) cannot, as configs
  cannot be part of .gni files.
