Revert of Add ETC1 powered SSE encoder for tile texture compression (patchset #23 id:440001 of https://codereview.chromium.org/1096703002/)

Reason for revert:
Speculative revert. Looks like this change breaks compilation on win8 GN:
http://build.chromium.org/p/chromium.win/builders/Win8%20GN

Failure Example:

Original issue's description:
> Add ETC1 powered SSE encoder for tile texture compression
>
> Created an ETC1 encoder that uses SSE2 to improve compression speed.
> The SSE encoder extends TextureCompressor and uses the same algorithm as TextureCompressorETC1.
>
> Added unittest for TextureCompressorETC1.
>
> Moved shared code into a etc1 header.
>
> Added new performance test scenarios.
>
> Performance difference on Ubuntu x64, Haswell Processor:
> Without SSE:
> *RESULT Compress256x256BlackAndWhiteGradientImage: ETC1 Low= 1.966321587562561 us
> *RESULT Compress256x256SolidBlackImage: ETC1 Low= .0956009104847908 us
> *RESULT Compress256x256SolidColorImage: ETC1 Low= .4367307722568512 us
> *RESULT Compress256x256RandomColorImage: ETC1 Low= 5.948055744171143 us

> With SSE:
