This patch adds support the kernel-irqchip option for
WHPX with on or off value. 'split' value is not supported
for the option. The option only works for the latest version
of Windows (ones that are coming out on Insiders). The
change maintains backward compatibility on older version of
Windows where this option is not supported.

Currently, TSC is set as part of the VM runtime state. Setting TSC at
runtime is heavy and additionally can have side effects on the guest,
which are not very resilient to variances in the TSC. This patch uses
the VM state to determine whether to set TSC or not. Some minor
enhancements for getting TSC values as well that considers the VM state.
Additionally, while setting the TSC, the partition is suspended to
reduce the variance in the TSC value across vCPUs.
