The sample count that vulkan and metal actually want to know is how
many samples the rasterizer will compute, which may not match the
number of samples in the render target when we have mixed samples.
They will also need to know whether a program is mixed sampled in
order to set up coverage modulation.

From now on, sample counts always refer to the number of actual color
samples, and render targets don't have separate color and stencil
sample counts.
If mixed samples support is available when making a
"GrAAType::kCoverage" draw, then an op may attach and use a mixed
sampled stencil buffer internally. But this will all be invisible to
the client.
After this CL, we temporarily won't have a mode to use nvpr with mixed
samples. That will soon be fixed by a follow-on CL that enables nvpr
with mixed samples in the normal "gl" and "gles" configs.

Previously, we relied on ops to deduce whether a draw would have
hardware coverage modulation as a result mixed samples. This is
problematic because *any* draw can have mixed samples coverage if
there is a multisampled stencil clip. No ops were checking for stencil
clip, and most just said they never used mixed samples.
Now that the only usecase for mixed samples is the stencil buffer,
this CL makes the processorSet automatically deduce mixed samples
coverage from the stencil settings and fsaaType.

GrRenderTargetOpList maintains an array of op chains. When it receives a
new op it tries to add it to an existing chain, working backwards from
the end of the current array. If the op can be added to a chain it
additionally tries to merge the new op with ops already in the chain
before adding it to the tail of the chain.
In forward combining it tries to concatenate chains. If chains can
concatenate it also attempts to merge ops between the two chains.
Now op chaining results reported by Op subclasses must be transitive.
Moreover, if op A is able to merge with B then it must be the case that
any op that can chain with A will either merge or chain with any op that
can chain to B.

Adds setVertexAttributes and setInstanceAttributes. These take a pointer
to the first attribute, and a count. The count is the total number of
possible attributes, though some may not be initialized. The base class
computes the number of initialized attributes, pre-computes the strides,
and only allows subsequent access to the initialized attributes.
The attributes need to be allocated contiguously. Some GPs place them in
an array, though most just place them as consecutive members, and pass
a pointer to the first one.
Indexed access would be possible, but now it makes more sense to iterate
over all attributes, so enable that, and use range-based for everywhere.
Completely remove the per-attribute offset helper (again - possible, but
not real helpful), and make the stride always available. In many ops,
just use the GP's computed stride, rather than re-computing it.
