Add GrExternalTextureData and SkCrossContextImageData

GrExternalTextureData is an API for exporting the backend-specific
information about a texture in a type-safe way, and without pointing
into the GrTexture. The new detachBackendTexture API lets us release
ownership of a texture to the client.

SkCrossContextImageData is the public API that lets clients upload
textures on one thread/GrContext, then safely transfer ownership to
another thread and GrContext for rendering.

Only GL is implemented/supported right now. Vulkan support requires
that we add thread-safe memory pools, or otherwise transfer the
actual memory block containing the texture to the new context.

Add SkColorSpace::isNumericalTransferFn() to the public API

This adds a little more flexibility for clients wanting to handle

Fix some viewer crashes when switching color mode

The whole idea of immediate mode GUIs is to put your GUI code and the
resulting action close together. Unfortunately, for actions that tear
down the backend (possibly freeing the surfaces we're drawing to), we
can't do that. So defer that action until the next frame (really, the
next idle). Only required when an action might call setDisplayParams.

gn_to_bp to recurse deps.

Currently gn_to_bp GrabDependentSrcs only grabs the top level deps of
a target. In a proposed change there are more levels of deps to
clarify the real dependencies. To make this work well, a number of
lists are now sets to avoid including the same file multiple times.

Change Comparator to switch on a direction enum instead of using function
pointers.

Inline sorted_merge() and front_back_split() into merge_sort(), and template
it on the comparator function, so it instantiates two versions. This
is even faster (but costs us some code bloat of course).

In Vulkan make sure resolve is sent to GPU when preparing msaa RenderTarget for external IO

In GrDrawingManager, when preparing for I/O we first flush the GPU then call resolve. However,
in Vulkan the resolve lives in a command buffer that needs to be flushed to the GPU as well.

This is most likely the cause we were seeing in Viewer app where first frame was always black
since the actually resolve command buffer was not flushed to the gpu before presenting. All
future frames would then typically show one frame behind.

Add AVX to the SkJumper mix.

AVX is a nice little halfway point between SSE4.1 and HSW, in terms
of instructions available, performance, and availability.

Intel chips have had AVX since ~2011, compared to ~2013 for HSW and
~2007 for SSE4.1.  Like HSW it's got 8-wide 256-bit float vectors,
but integer (and double) operations are essentially still only 128-bit.
It also doesn't have F16 conversion or FMA instructions.

It doesn't look like this is going to be a burden to maintain, and only
adds a few KB of code size.  In exchange, we now run 8x wide on 45% to
70% of x86 machines, depending on the OS.

In my brief testing, speed eerily resembles exact geometric progression:
   SSE4.1:        1x speed (baseline)
      AVX: ~sqrt(2)x speed
      HSW:       ~2x speed

This adds all the basic plumbing for AVX but leaves it disabled.
I'll flip it on once I've implemented the f16 TODOs.
