Revert of WebGL: use storage texture for DrawingBuffer only if CMAA is enabled.

Revert of WebGL: use storage texture for DrawingBuffer only if CMAA is enabled. (patchset #3 id:60001 of https://codereview.chromium.org/2131863003/ )

Reason for revert:
ATI GPU bots became green, no matter this CL. ATI GPU bot might be in bad shape for some reasons.
So revert this redundant speculative fix.

A revert of this CL (patchset #1 id:1) has been created in
https://codereview.chromium.org/2143423002/ by dongseong.hwang@intel.com.

The reason for reverting is: ATI bot failed due to this CL.

ATI bot was fine because we disabled
WebglConformance.conformance_textures_misc_tex_image_webgl
However, https://codereview.chromium.org/2141893002/ enabled the test again, so
this CL must be reverted..
