This further consolidates the information required to compute the program key (esp. for Vulkan). This CL mainly comprises the plumbing portion - a follow up CL will actually use it.

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().

- Update the parameter lists to both run and runStriped so
that they're in the same (sane) order, named consistently,

- Add the same count-based safety checks to run that were
already in runStriped.
- Remove the N parameter to run, it was only used to run
things one-at-a-time (other than one spot in unit tests),
and it simplifies the code quite a bit. If you want to run
multiple times, use the striped version. I also moved that
functions 'N' earlier in the parameter list, to make the
pattern of the remaining parameters clearer.
- Remove an interpreter benchmark class that was never used.

2x faster than calling drawVertices as the impl.
Lots more to do in future CLs
- much of the time is spent in malloc, as we cons-up private shaders.
we *could* create a private shader and wack its data for each draw
(breaking the immutable contract, but that may be ok for a raster-only
internal-use shader...)
- also spend time building the pipeline for each draw, even though
all that has changed is a color payload (and the ctm). A custome
stage(s) that exposed its private data could be reused with new
data...
