commit 5cf9bd2b9e7713034d798e6aed304124d9a694fd

Revert of Enforce constant size and device scale factor for surfaces (patchset #16 id:800001 of https://codereview.chromium.org/2848223003/ )

Reason for revert:
Suspect this breaks SurfaceAggregatorPerfTest

BUG= 725840 

Original issue's description:
> Enforce constant size and device scale factor for surfaces
>
> Surfaces are expected to have constant size and device scale factor but
> we don't enforce that. This CL requires a valid SurfaceInfo to be
> provided at the time of constructing a surface, and all frames that don't
> match the SurfaceInfo will be skipped.

Is there no information about what's crashing or the callstack?

Reland "Enforce constant size and device scale factor for surfaces" with fixes

The original CL(crrev.com/2848223003) surfaced two problems that this CL
fixes:
- SurfaceAggregatorPerfTest sends frames with zero size and device scale
factor
- SurfacesInstance does not properly allocate new LocalSurfaceIds.
