versions: Update firecracker version to 1.8.0

This PR updates the firecracker version to 1.8.0 which includes the
following changes:
- Added ACPI support to Firecracker for x86_64 microVMs. Currently, we pass ACPI tables with information about the available vCPUs, interrupt controllers, VirtIO and legacy x86 devices to the guest. This allows booting kernels without MPTable support. Please see our kernel policy documentation for more information regarding relevant kernel configurations.
- Added support for the Virtual Machine Generation Identifier (VMGenID) device on x86_64 platforms. VMGenID is a virtual device that allows VMMs to notify guests when they are resumed from a snapshot. Linux includes VMGenID support since version 5.18. It uses notifications from the device to reseed its internal CSPRNG. Please refer to snapshot support and random for clones documention for more info on VMGenID. VMGenID state is part of the snapshot format of Firecracker. As a result, Firecracker snapshot version is now 2.0.0.
- Changed T2CL template to pass through bit 27 and 28 of MSR_IA32_ARCH_CAPABILITIES (RFDS_NO and RFDS_CLEAR) since KVM consider they are able to be passed through and T2CL isn't designed for secure snapshot migration between different processors.
- Avoid setting kvm_immediate_exit to 1 if are already handling an exit, or if the vCPU is stopped. This avoids a spurious KVM exit upon restoring snapshots.
- Changed T2S template to set bit 27 of MSR_IA32_ARCH_CAPABILITIES (RFDS_NO) to 1 since it assumes that the fleet only consists of processors that are not affected by RFDS.
