arch/x86/assembly_entry: allow early post CAR stages to use common code
The skylake-based Chromebooks use a separate verstage which runs just after bootblock and prior to romstage. The normal path for romstage would be to reload the gdt, however in the previously described scenario has verstage performing that work. Therefore, provide that path under those conditions. The only difference from the C_ENVIRONMENT_BOOTBLOCK scenario is that the stack should not be reloaded since there's no way to know the top of the stack.
