CHERRY-PICK: hypervisor: x86: kvm: change TSC once during restore

Initially, time was not being restored in the VM unless we restore the
offset. This was possibly due to a different bug, where we weren't
restoring all the MSRs.

Bug:327278462
Test: boot crosvm. snapshot. restore. check time of VM == time of snapshot.
Test: boot CF, snapshot CF. Restore CF.

crosvm - The ChromeOS Virtual Machine Monitor

crosvm is a virtual machine monitor (VMM) based on Linux’s KVM hypervisor, with a focus on simplicity, security, and speed. crosvm is intended to run Linux guests, originally as a security boundary for running native applications on the ChromeOS platform. Compared to QEMU, crosvm doesn’t emulate architectures or real hardware, instead concentrating on paravirtualized devices, such as the virtio standard.

crosvm is currently used to run Linux/Android guests on ChromeOS devices.
