Revert of Fix setColocatedSampleLocations on ES and GL < 4.5 (patchset #2 id:20001 of https://codereview.chromium.org/1415503008/ )

Reason for revert:
Co-centered sample locations are not needed to do stencil clip with mixed samples.

Original issue's description:
> Fix setColocatedSampleLocations on ES and GL < 4.5
>
> Updates setColocatedSampleLocations to use glFramebufferParameteri
> when
> the DSA version glNamedFramebufferParameteri is not present.
