feat(axalloc): introduce a global memory allocator with buddy system

- Added `axalloc` crate with a global allocator implementation.
- Implemented `GlobalAllocator` using a buddy system allocator.
- Provided functions for memory initialization, allocation, and deallocation.
- Added `GlobalPage` struct for managing contiguous memory pages.

feat(axvm-types): define address types and device access structures

- Introduced `GuestVirtAddr` and `GuestPhysAddr` types for guest memory addressing.
- Created traits for device address handling and defined `DeviceAddr` and `DeviceAddrRange`.
- Implemented `Port` and `SysRegAddr` types for I/O operations and system registers.

fix(vmm): update VM reference handling

- Changed `push_vm` function to accept `axvm::Vm` directly and return an `Arc<axvm::Vm>`.
- Updated global VM list management to use `Arc` for thread-safe reference counting.

chore: update submodules and dependencies

- Updated submodules for `arm_vcpu`, `axvm`, and `axvmconfig`.
- Added `memory_addr` dependency to `axruntime` and `axvm-types`.
- Updated `Cargo.toml` files to reflect new dependencies and features.
