Add support for vertex and geometry shader textures

Adds a visibility bitfield to GrTextureAccess that controls in which
shaders the texture should be accessible. Also adds caps and
validation to ensure we don't exceed texture limits.

     /** Appends a 2D texture sample with projection if necessary. coordType must either be Vec2f or
         Vec3f. The latter is interpreted as projective texture coords. The vec length and swizzle
         order of the result depends on the GrTextureAccess associated with the GrGLSLTextureSampler.
