This commit moves struct acrn_vm under common header vm.h, and move some x86-specific members of struct acrn_vm into arch_vm. This commit focuses on struct cleanup only. API cleanup will be in future patch series. The affected members are: e820_entry_num e820_entries wire_mode wbinvd_lock vlapic_mode_lock vcpuid_entry_nr vcpuid_level vcpuid_xlevel vcpuid_entries reset_control pm sworld_control sworld_snapshot intr_inject_delay_delta Moved to common vm.h: ept_lock -> rename to stg2pt_lock ept_pgtable -> rename to stg2_pgtable nworld_eptp -> rename to root_stg2ptp emul_mmio_lock nr_emul_mmio_regions emul_mmio emul_pio To avoid circular dependency, some in-header helpers are also moved into common vm.h.
