refactor(kernel): Standardize DMA and AHCI interfaces and enhance GIC handling

- Replace ambiguous WordLength templates with DataKind in `ke_dma_read/write`.
- Streamline AHCI driver initialization by directly assigning port implementations.
- Rename AHCI methods for clarity (`SetPi` → `SetPortsImplemented`).
- Standardize MMIO access by replacing `hal_mmio_read/write` with unified `ke_dma_read/write`.
- Improve GIC interrupt handler on ARM64 by explicitly handling scheduler interrupts and ensuring interrupts are ended correctly.
- Add debug breakpoint in infinite loop within AP setup for improved debugging.
