Revert of Make "priv" classes for GrTexure and GrSurface. (patchset #9 id:260001 of https://codereview.chromium.org/596053002/)

Reason for revert:
Breaking the Chrome builds with:

 lib/libcc.so: error: undefined reference to 'GrAutoScratchTexture::detach()'

(http://108.170.220.120:10117/builders/Canary-Chrome-Ubuntu13.10-Ninja-x86_64-DRT/builds/2990/steps/Retry_BuildContentShell_1/logs/stdio)
