Revert of Add factory class for generating various flavors of GrTextContext. (https://codereview.chromium.org/144283002/)

Reason for revert:
Breaks Chrome. Need to fix template issue.

Original issue's description:
> Add factory class for generating various flavors of GrTextContext.
>
> This is the first pass of making Gr*TextContext more generic and easily
> subclassed. The next stage will be making GrBitmapTextContext and
> GrDistanceFieldTextContext more similar by moving the SkDraw loop into
> each subclass.
