Adds the ability for GLInstancedRendering to use
glDrawElementsInstanced when glDrawElementsIndirect is not supported.
The only remaining 3.1 dependency now is EXT_texture_buffer.
Also moves the cap for glDraw*Instanced out of GrCaps and into
GrGLCaps.

Updates stencilRect to call drawNonAAFilledRect instead of
drawFilledRect. drawFilledRect can use coverage AA, which isn't
appropriate for stencil draws. Also modifies drawNonAAFilledRect to
take a "useHWAA" argument instead of trying to deduce whether it
should be used.

On Debug vulkan bots, running with the debug layers on seems to be adding
more than an hour to the total running time. Since we suppress any output
on the bots anyways the debug layers are serving no purpose. Thus I am
adding a gyp define to disable the layers on the bot.
With this change, by default when running vulkan in Debug, the debug_layers
will be enabled. The bots should disable the layers. Android framework
should also have them disabled by default.

DrawContext's isGammaCorrect now just based on presence of color space.
Next change will remove the function and flag entirely, but I wanted to
land this separately. This alters a few GMs in srgb/f16 mode, generally
those that are creating off-screen surfaces in ways that were somewhat
lossy before. No unexplained changes.

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.

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.

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.).

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.

Updates GrDrawContext to crop filled rects to the clip bounds before
creating batches for them. Also adds clipping logic to ignore scissor
when the draw falls completely inside. These two changes combined
reduce API traffic and improve batching.
In the future this can and should be improved by switching to floating
point clip boundaries, thus allowing us to throw out non pixel aligned
rectangle clips as well.

Adds a module that performs instanced rendering and starts using it
for a select subset of draws on Mac GL platforms. The instance
processor can currently handle rects, ovals, round rects, and double
round rects. It can generalize shapes as round rects in order to
improve batching. The instance processor also employs new drawing
algorithms, irrespective of instanced rendering, that improve GPU-side
performance (e.g. sample mask, different triangle layouts, etc.).
This change only scratches the surface of instanced rendering. The
majority of draws still only have one instance. Future work may
include:
* Passing coord transforms through the texel buffer.
* Sending FP uniforms through instanced vertex attribs.
* Using instanced rendering for more draws (stencil writes,
drawAtlas, etc.).
* Adding more shapes to the instance processor’s repertoire.
* Batching draws that have mismatched scissors (analyzing draw
bounds, inserting clip planes, etc.).
* Bindless textures.
* Uber shaders.
