Revert of Fix GPU clipped-AA vs. non-AA drawRect discrepancy (patchset #2 id:20001 of https://codereview.chromium.org/839883003/)

Reason for revert:
This CL introduces rendering conflicts with hairlines (i.e., the hairlines get overwritten). These conflicts are particularly visible on the following GMs (for the Ubuntu and Android gpu configs):

coloremoji & complexclip2_rrect_bw

Original issue's description:
> Fix GPU clipped-AA vs. non-AA drawRect discrepancy
>
> In the clip stack we were manually rounding out non-AA clip rects but leaving the hardening of non-AA drawRects up to the GPU. In some border cases the GPU can truncate rather than round out resulting in visual discrepancies.
