Revert of Extract most of the mutable state of SkShader into a separate Context object. (https://codereview.chromium.org/207683004/)
Reason for revert:
This is blocking the DEPS roll into Chromium. Failures can be seen here:

Original issue's description:
> Extract most of the mutable state of SkShader into a separate Context object.
>
> SkShader currently stores some state during draw calls via setContext(...).
> Move that mutable state into a separate SkShader::Context class that is
> constructed on demand for the duration of the draw.
>
> Calls to setContext() are replaced with createContext() which returns a context
> corresponding to the shader object or NULL if the parameters to createContext
> are invalid.
