Revert of cc: Added RED_8 to the ResourceFormat enum

Revert of cc: Added RED_8 to the ResourceFormat enum (patchset #2 id:20001 of https://codereview.chromium.org/735493003/)

Reason for revert:
Reverting the CL because it broke the CrOS ozone compile. See http://build.chromium.org/p/chromium.chromiumos/builders/Linux%20ChromiumOS%20Ozone%20Builder/builds/7795/steps/compile/logs/stdio

Original issue's description:
> cc: Added RED_8 to the ResourceFormat enum
>
> New ResourceFormat, RED_8, which translates to GL_UNSIGNED_BYTE on format
> GL_RED_EXT.  This will be used during YUV playback.
>
> At the moment nothing uses it.
