Revert "[LaCrOS]Disable usage of linux_explicit_synchronization for now"

This reverts commit 500376ce.

Reason for revert: crbug.com/1144179 has been fixed, we no longer make consecutive subsurface commits with fences.

Original change's description:
> [LaCrOS]Disable usage of linux_explicit_synchronization for now
>
> linux_explicit_synchronization can cause crash due to a bug in earlier
> exo version. Underlying issue can be fixed from lacros side. Re-enable
> once fix is landed.
