We think this might be more flexible. It allows, e.g, function-level blacklisting,
and here an easy one-stop-shop blacklist for all of third_party/externals.

Seems like GrContextFactory needs to fail when the NVPR option is requested but the driver version isn't sufficiently high.

Make NVPR a GL context option instead of a GL context.
This may enable NVPR to be run with command buffer
interface.
No functionality change in DM or nanobench. NVPR can
only be run with normal GL APIs.

Replaces "nvpr mode" with "offscreen mode" and a flag to enable/
disable nvpr. Assigns new config names to the various combinations of
flags and begins printing them with the bench results in order to match
nanobench.

Modifies NvprWrappedBenchmark to present its offscreen canvas via
GrContext::copySurface rather than going through the SkCanvas API.
Only copies a subrectangle the size of the benchmark, not the entire
canvas.

DIVBITS_ITER was shifting bits up into the sign bit, which is a no-no.
This turns numer into a uint32_t to make those defined, and adds a few notes.
x >= 0 is always true for unsigned x, so we needed a few small logic refactors.
