This allows us to create integer textures and sample them from a GrProcessor's code.
Filtering is limited to NEAREST.
Adds tests for reading/writing pixels, copying, and drawing. These operations are not allowed to convert to fixed/float configs.
Vulkan support is TBD.

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.).

The purpose is to begin separating our GLSL-specific code from
our GL-specific code, so it can be used with the GL45 platform
