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

This reverts commit 7b896836.

Reason for revert: Lots of test failures on current roll:
https://chromium-review.googlesource.com/c/chromium/src/+/1534141

Original change's description:
> Reland "[ptr-compr][x64] Temporarily enable pointer compression on x64"
> 
> This is a reland of 4f051fd5
> 
> Relanding because last revert was caused by unrelated flakes.
