Revert of Implement text rendering with NVPR (https://codereview.chromium.org/196133014/)

Reason for revert:
This probably caused Win8 test bot fail during gm run:

http://108.170.217.252:10117/builders/Test-Win8-ShuttleA-GTX660-x86-Debug/builds/574

I can not identify any errors from the logs, so maybe it hung or something?

Original issue's description:
> Implement text rendering with NVPR
>
> Use path rendering to render the text from outlines if supported by the
> GPU. Implement this in GrStencilAndCoverTextContext by copying large
> chunks of code from GrBitmapTextContext (drawText) and
> GrDistanceFieldTextContext (drawPosText).
>
> The drawing is implemented with "instanced" path drawing
> functions.
>
> Moves the creation of the "main" text context from SkGpuDevice to the
> GrContext::createTextContext. This is done because the decision of which
> text renderer is optimal can be made only with the internal
> implementation-specific information of the context.
>
> Committed: http://code.google.com/p/skia/source/detail?r=13962
