This reverts commit bd9ac13a.

Reason for revert: Unfortunately there's another V8 CL close which massively affects speedometer. We need to reland to get a clear picture.

Original change's description:
> [oilpan] Enable incremental marking buildflag
> 
> Includes incremental garbage collection infrastructure in regular
> builds. Does not enable incremental marking at runtime!
> 
> This CL may cause throughput regressions and is an attempt
> to collect a broad range of potential performance issues.
