acpi: x86: add option for setting LP S0 capable flag for guest ACPI tables

Fixed ACPI Description Table (FADT) contains Low Power S0 Idle Capable
Flag. This commit introduces "--s2idle" argument allowing to set proper
bit in the guest FADT table. This is required to inform guest OS to use
s2idle instead of traditional S3 power mode.

BUG=b:194391015
TEST=Build crosvm and run "crosvm run --s2idle ..", dump FADT table and
     confirm that proper flag was set.

crosvm - The Chrome OS 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 Chrome OS 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 Chrome OS devices.
