Certain systems experience a leak in the GL driver associated with
stencil buffers. Attempts to avoid the leak (while still using stencil
buffers) dind't succeed. This patch adds a GrContextOption
fAvoidStencilBuffers. This disables certain path rendering modes, as
well as stencil based masking/clipping.

A single glyph cache size doesn't make sense across the hardware Skia
runs on. This change allows a custom size to be specified (via a byte
limit), allowing cache size to be customized at context creation time.

Adds a bitfield to GrContextOptions that masks out path renderers.
Adds commandline flags support to set this bitfield in tools apps.
Removes GrGLInterfaceRemoveNVPR since we can now accomplish the same
thing in the context options.

Rob and I spent a long time debugging why this wasn't working for
Flutter - doing the more complex operations on the loading thread
produces a blank texture when it's used later on the drawing thread.
Limiting ourselves to just creating and uploading RGBA data fixes
that. We need to debug what's going wrong, but in the meantime, this
lets Flutter use Skia APIs to manage GPU uploading and lifetime of
texture-backed images, while still doing those uploads on their IO
thread.

1) Our older iOS devices failed our sRGB tests, due to precision issues
with alpha. At this point, we only test on iPadMini 4, and that appears
not to have any problems.
2) iOS devices still don't have the sRGB texture decode extension. But,
some clients have no interest in mixing legacy/color-correct rendering,
and would like to use sRGB on these devices. This GrContextOptions flag
enables sRGB support in those cases.
Adjust the test code to produce sRGB capable contexts on these devices,
but only for configs that have a color space. (See comment).

This allows internal Gr texture creation code to succeed for extraneous textures while running the bleed GM. This means we can turn on the shader variants.
Review URL: https://codereview.chromium.org/1418473004
Removes the runtime logic used by PorterDuffXferProcessor to decide
blend coeffs and shader outputs, and instead uses a compile-time
constant table of pre-selected blend formulas. Separates out the dst
read fallback into its own XP.
Introduces a new blend strategy for srcCoeff=0 that can apply coverage
with a reverse subtract blend equation instead of dual source
blending.
Adds new macros in GrBlend.h to analyze blend formulas both runtime.
Removes kSetCoverageDrawing_OptFlag and GrSimplifyBlend as they are no
longer used.
Adds a GM that verifies all xfermodes, including arithmetic, with the
color/coverage invariants used by Porter Duff.
Adds a unit test that verifies each Porter Duff formula with every
color/coverage invariant.
Major changes:
* Uses a reverse subtract blend equation for coverage when srcCoeff=0
(clear, dst-out [Sa=1], dst-in, modulate). Platforms that don't
support dual source blending no longer require a dst copy for
dst-in and modulate.
* Sets BlendInfo::fWriteColor to false when the blend does not modify
the dst. GrGLGpu will now use glColorMask instead of blending for
these modes (dst, dst-in [Sa=1], modulate ignored for [Sc=1]).
* Converts all SA blend coeffs to One for opaque inputs, and ISA to
Zero if there is also no coverage. (We keep ISA around when there
is coverage because we use it to tweak alpha for coverage.)
* Abandons solid white optimizations for the sake of simplicity
(screen was the only mode that previous had solid white opts).
Minor differences:
* Inconsequential differences in opt flags (e.g. we now return
kCanTweakAlphaForCoverage_OptFlag even when there is no coverage).
* Src coeffs when the shader outputs 0.
* IS2C vs IS2A when the secondary output is scalar.
