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

Introduce GrColorSpaceXform, for gamut conversion on textures

GrTextureAccess optionally includes an instance, computed from the src
and dst color spaces. In all common cases (no color space for either src
or dst, or same color space for both), no object is allocated.

This change is orthogonal to my attempts to get color space attached to
render targets - regardless of how we choose to do that, this will give
us the source color space at all points where we are connecting src to
dst.

There are many dangling injection points where I've been inserting
nullptr, but I have a record of all of them. Additionally, there are now
three places (the most common simple paths for bitmap/image rendering)
where things are plumbed enough that I expect to have access to the dst
color space (all marked with XFORMTODO).

In addition to getting the dst color space, I need to inject shader code
and uniform uploading for appendTextureLookup and friends.

pathops coincidence and security rewrite

Most changes stem from working on an examples bracketed
by #if DEBUG_UNDER_DEVELOPMENT  // tiger
These exposed many problems with coincident curves,
as well as errors throughout the code.

Fixing these errors also fixed a number of fuzzer-inspired
bug reports.

* Line/Curve Intersections
Check to see if the end of the line nearly intersects
the curve. This was a FIXME in the old code.

* Performance
Use a central chunk allocator.
Plumb the allocator into the global variable state
so that it can be shared. (Note that 'SkGlobalState'
is allocated on the stack and is visible to children
functions but not other threads.)

* Refactor
Let SkOpAngle grow up from a structure to a class.
Let SkCoincidentSpans grow up from a structure to a class.
Rename enum Alias to AliasMatch.

* Coincidence Rewrite
Add more debugging to coincidence detection.
Parallel debugging routines have read-only logic to report
the current coincidence state so that steps through the
logic can expose whether things got better or worse.

More functions can error-out and cause the pathops
engine to non-destructively exit.

* Accuracy
Remove code that adjusted point locations. Instead,
offset the curve part so that sorted curves all use
the same origin.
Reduce the size (and influence) of magic numbers.

* Testing
The debug suite with verify and the full release suite
./out/Debug/pathops_unittest -v -V
./out/Release/pathops_unittest -v -V -x
expose one error. That error is captured as cubics_d3.
This error exists in the checked in code as well.

Add a bench to measure the best way to pack from int to uint16_t with SSE.

I measured relative runtimes on my laptop:

   pack_int_uint16_t_ss…
   1036  …e41 1x  …se3 1.01x  …e2_b 3.01x  …e2_a 3.02x

I've run into Clang problems with the actual _mm_packus_epi32 instruction, I think,
so I'm going to exercise a little cowardice and leave that option disabled for now.

The ssse3 version probably looks a little faster than it will be in practice.
We'll usually need to load its mask, which here is hoisted out of the bench loop.

The two sse2 variants are close enough in speed that I'm tie breaking them on other
concerns: the <<16, >>16 version doesn't need any scratch registers or to load any
constants, so it wins.

Add Texture2D and Sampler GrSLTypes

These two new types are in support of Vulkan and the ability to send
separate texture and sampler uniforms to the shader. They don't really fit
well in the current system, since the current system ties together to idea
of intended use and how to emit shader code into the same GrSLType enum.

In vulkan, I want the GrGLSLSampler object to be used as a Sampler2D, but
when appending its declaration it will emit a Texture2D and sampler object.

Our query for GrSLTypeIsSamplerType refers more to the combination of texture
and sampler and not just the sampler part. The GrSLTypeIs2DTextureType query
is for is a a SamplerType that uses Texture2Ds. My new types don't really fit
into either these categories as they are just half of the whole.

In some refactoring down the road (possibly connected with SkSL), I suggest we
split apart the concept of how we intend to use a GrGLSLSampler (Sampler2D, SamplerBuffer,
etc.), from how we actually add it to the code (sampler, texture2D, sampler2D, etc.).

Disable embedded bitmap test on iOS.

The TypefaceRenderingGM crashes on iOS when drawing an embedded
bitmap when requesting aliased rendering. The crash looks like

libTrueTypeScaler.dylib`<redacted> + 80
stop reason = EXC_BAD_ACCESS (code=EXC_ARM_DA_ALIGN, address=...)
->  0x330b19d0 <+80>: strd   r2, r3, [r5, #36]
    0x330b19d4 <+84>: movs   r3, #0x0
    0x330b19d6 <+86>: add    r2, sp, #0x28
    0x330b19d8 <+88>: ldr    r0, [r4, #0x4]

Disable testing embedded bitmaps on iOS for now.

Fix vertex count estimate in GrTessellator.

When we start a new MonotonePoly due to a handedness change, we don't need to
increase the vertex count, since that edge (and vertex) has already been
accounted for in the previous MonotonePoly.

This was not a correctness issue, but was causing us to allocate
extra vertices which would go unused.

Add resource provider flag to avoid client-side buffers

On some platforms, a newly-created buffer was liable to be CPU backed.
This would break code that expected a VBO (aka instanced rendering).
This change adds an optional flag to GrResourceProvider that requires
a buffer to be created in GPU memory.

It also moves the CPU backing logic into Gr land in order to properly
cache real VBOs on platforms that prefer client-side buffers.

Turn back on nanobench on Debug trybots.

Swarming makes the extra wall-clock cost negligible.
