Refactor VM and vCPU structures; remove unused HAL trait

- Deleted the `hal.rs` file and removed references to `AxVMHal` from `lib.rs`.
- Consolidated VM ID handling into a new `VmId` struct in `vm.rs`, removing the duplicate definition in `vm2.rs`.
- Introduced a `VmOps` trait for VM operations and a `Status` enum to represent VM states.
- Removed the `AxVM` struct's internal implementation details, focusing on the public API for VM management.
- Cleaned up the `vcpu.rs` file by commenting out unused architecture-specific code.
- Reduced complexity in the `vm.rs` file by removing unnecessary fields and methods related to memory management.
