c241b58965 Make fragment processor iterators work with range for loops.
When iterating over the coord transforms or texture samplers of a
FP also have access to the owning FP.

Pass a coord transform range to GPs rather than a pointer to an
iterator.

5e8cdfdd8b Add 'numRasterSamples' and 'isMixedSampled' to GrProgramInfo
Replaces numSamples with numRasterSamples, and adds isMixedSampled.
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.

6ce447a4ec Eliminate mixed samples as an FBO type or AA type
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.

   - removed -Idirectives from BUILD.gn
   - various compile.sh simplifications
   - tweak tools/embed_resources.py
   - update gn/find_headers.py to write paths from the top
   - update gn/gn_to_bp.py SkUserConfig.h layout
     so that #include "include/config/SkUserConfig.h" always
     gets the header we want.

b8fff0dfce Make mixed samples detection automatic
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.

dbf7072a59 Use different classes for client side arrays and GPU buffer objects.
GrBuffer is a base class for GrGpuBuffer and GrCpuBuffer. GrGpuBuffer is a
GrGpuResource and the others are not. This allows GrCpuBuffers to exist
outside of the GrGpuResourceCache.

Also removes flags from GrResourceProvider buffer factory function. The
only flag still in use was kRequireGpuMemory. Now CPU buffers are made
without using GrResourceProvider.

588cec7f91 Reenable GrOp chaining.
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.
