This CL is 100% plumbing. We ultimately want all GrPrimitiveProcessor-derived objects to not be refCounted. This will make several helper objects POD and, by putting them into an arena, will make managing their lifetime easier (e.g., for DDL prePreparing).
Note: the CCPR GrGeometryProcessor-derived classes only ever appear on the stack so aren't forced into arenas.

It appears that the Mac glyph rasterizer doesn't work well with our
AA-based SDF generator -- the SDFs produced have more aliasing than
expected. This CL changes the Mac to use 256 as its highest SDF size,
and only scale down from there.
More work may need to be done -- the best solution may be to generate
the SDFs directly from the path rather than the rasterized glyph.

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.

As we've learned there's not much advantage to working directly in i32
ops over f32... it's the same size, kind of a wash speed-wise, and f32
supports all operations we want where i32 supports only a subset. If we
really want to go fast, we need to focus on i16 operations, which are
both significantly faster and operate on twice as much data at a time.
(This is the same split as SkRasterPipeline, highp f32 and lowp i16.)
For now port everything to f32, with i16 to follow, perhaps much later.
There's a little here we could spin off to land first (uniformF, better
unpremul) but I think it might be easiest to land all at once.

This basically wraps up the old `uniforms` and `buf` params

It's clearer and more efficient to emit uniforms
as we use them. The pattern to look for is something like
skvm::I32 val = p->uniform32(uniforms, buf->bytes());
buf->push_back(fVal);
where fVal holds the actual uniform value, and val is its program
counterpart.
Switching to SkTDArray lets us use friendlier methods like bytes() and
append(N) in the effect code.
It's a lot easier to follow this way once you get used to it and much
less error-prone. No need to split the can-we-do-it logic up from the
uniform emission, and so no chance to write logic twice that
acccidentally disagrees.
Effects now always emit uniforms when you call program(), which means we
occasionally do that twice, once when building the Key to look up cached
programs, and once again when building the program if the cache misses.
That's not that big of a deal... it reuses the same memory exactly, and
I've added some notes around the code and assertions that everything
matches up exactly. It only happens on cache miss, so it's dwarfed by
the cost of building and JITing the program anwyay.

By making uniforms() just append to the uniform vector, there's no more
need for two passes, no need for the blitter to ever even know how many
uniforms the effects use, and the effects now never need to deal with a
nullptr uniform buffer. Much simpler all around.
While we're refactoring, convert the uniform buffer de jure to
std::vector<uint32_t>, which is what we'd been treating the old
std::vector<uint8_t> as by convention, and switch the program() offset
parameter type to size_t as a reminder that it's measured in bytes.

This reverts commit ce240cc6fd.
Reason for revert: crashing in chrome unit test, abandoned context related?

Previously the pixel data passed to the client was only valid during
the client's callback. This meant if the client wanted to defer
processing of the data a copy was necessary.
Now we pass an object to the callback and the pixel lifetime is tied
to the lifetime of that object.
The object may be holding a GPU transfer buffer mapped. We don't assume
that the object will be released on the direct GrContext thread. So
when the object is destroyed it posts a message to a new type,
GrClientMappedBufferManager, hanging off the direct context. The direct
context will periodically check for messages and unmap and then unref
buffers so that they can be reused. Currently this is done in
GrContext::performDeferredCleanup() and GrDrawingManager::flush().
The old API is kept around for backwards compatibility but it is
reimplemented as a bridge on top of the new mechanism.
Also a utility function to SkImageInfo is added to directly make a new
info with a specified dimensions rather than passing the width and
height separately to makeWH().

Add version SkImageInfo::Make() that takes SkISize instead of separate
width and height.
