For hypervisors it's automatic. For operating systems, there's no performance penalty. Browsers need not do anything.

It's still the hypervisor (Hyper-V in that case) that has to do the work to mitigate the vulnerability, not the browser. The browser just uses whatever APIs the hypervisor exposes to create a virtual machine.
