Revert of Fix ClipMaskManager's SW-fallback logic

Revert of Fix ClipMaskManager's SW-fallback logic (patchset #4 id:60001 of https://codereview.chromium.org/1421533007/ )

Reason for revert:
Logic may be incorrect

Original issue's description:
> Fix ClipMaskManager's SW-fallback logic
> 
> 
> 'useSWOnlyPath' was not correctly toggling between stencil and color draws so there was a mismatch with the behavior in createAlphaClipMask (i.e., we were inadvertently rendering some of the elements in a clip using SW but using stenciling for others - precisely what 'useSWOnlyPath' was intended to prevent).
