kernel: Refactor AHCI I/O path, enhance memory allocators, and cleanup obsolete script

- Removed unused `build_gcc.sh` script.
- Namespaced CPU feature flags under `NeOS` and transitioned from enum to unnamed enum for scoping.
- Renamed `drv_std_input_output` to `drv_std_input_output_ahci` for clarity.
- Improved AHCI driver documentation and added zeroing for read buffers.
- Added optional `pad` parameter to memory allocators: `mm_alloc_bitmap`, `mm_new_heap`, `PageMgr::Request`, etc.
- Updated bitmap allocator to correctly handle and align with padded sizes.
- Added `fPad` field to memory header block.
- Fixed `ATA-DMA` mode comment, corrected PRD usage and logic.
- Improved code documentation and formatting in `UserProcessScheduler`, `PageMgr`, and related components.
- Enhanced safety in process memory cleanup (e.g., `StackReserve` cleanup).
