Use fixed function pipeline only when drawing paths. Previously FF
vertex shader was used when drawing normal geometry if path rendering
was enabled.
This is required to make Chromium integration easier. This way
fixed function vertex shading, including vertexshader-less programs,
need not be implemented in the Chromium command buffer.
Removes FF TexGen functionality, as it is not used anymore. Likewise
removes the fixedFunctionSupport GL capability flag.

Adds support for vertexless shaders and enables them when
NV_path_rendering is available. This takes a
GrGLFragmentOnlyShaderBuilder class, a GrGLTexGenEffectArray class,
support for setting TexGen and the projection matrix in GrGpuGL, and
code for setting the GL fixed function state where necessary.

Removes the VertexBuilder nested class from GrGLShaderBuilder in favor
of a new GrGLFullShaderBuilder subclass, and adds an optional emitCode
overload to GrGLEffect that takes a GrGLFullShaderBuilder. Makes
setData virtual in GrGLEffectArray and adds a GrGLVertexEffectArray
subclass that gets built using a GrGLFullShaderBuilder. Also adds a
new GrGLVertexEffect subclass that makes the GrGLFullShaderBuilder
overload required for emitCode, and updates GrGLEffects to inherit
from GrGLVertexEffect where needed.

Before, gradients would only interpolate the linear portion of the
quadratic equation if there was no perspective. This updates them to
do so even in the case that there is perspective. The rearrangement
of math causes noise differences in the following gm tests:
gradients_no_texture_gpu
gradients_view_perspective_gpu
gradients_local_perspective_gpu
gradients_gpu

Creates a GrGLProgramEffects class that the GrGLProgram uses to manage
an array of effects. This gives us enough abstraction for the program
to cleanly handle different types of coord transforms.
