Revert "Reland "[ptr-compr][x64] Temporarily enable pointer compression on x64""

Browse Source 
This reverts commit 42beed975e.

Reason for revert: This commit seems to cause consistent failures in
some ProcessMemoryMetricsEmitterTest tests on Mac and ChromeOS. I'm
not sure what the exact reasoning behind this is. See https://crbug.com/949157.

Original change's description:
> Reland "[ptr-compr][x64] Temporarily enable pointer compression on x64"
>
> This is a reland of 4f051fd5da
>
> Relanding after fixing Chromium issues.

> Original change's description:
> > [ptr-compr][x64] Temporarily enable pointer compression on x64
> >
> > ... and make sure that the x64 ptr-compr bots proceed testing V8 without
> > pointer compression in order to keep testing the full pointer mode.
