Move VertexBuilder to a GrGLFullShaderBuilder subclass
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.
