Default hasher foldhash queries the time

Describe the bug

The recent update to foldhash as the default hasher for map in v0.8.6 introduces a dependency on std::time within foldhash. This poses a problem for targets like zkvm, where time is not available, leading to errors.

This change effectively breaks compatibility with zkvm and potentially other targets lacking std::time. Projects relying on Alloy and targeting these platforms will no longer work successfully.

I've removed the default in #771, but this is also the default hasher for Hashbrown, so consider opening an issue/PR in foldhash to extend disabling the time query cfg

[DaniPopes]

I've reverted #771 but gated the default hasher to not include target_os = "zkvm" in #777. I would still recommend making the fix in foldhash since you would encounter this in any hashbrown 0.15 usage.
