cuFile calls were scattered directly in aiori-POSIX.c. Move them into two layers: - gpu_runtime.h / cuda_runtime.c: wraps cudaMalloc, cudaFree, etc. - gpu_io.h / gpu_io_cufile.c: wraps cuFile driver, register, read/write aiori-POSIX.c now calls only gpu_io_* / gpu_runtime_*. configure.ac: --with-cuda=PREFIX and --with-cufile=PREFIX with proper save/restore. --with-gpu-direct-backend=cufile|none replaces --with-gpuDirect (kept as alias). HAVE_GPU = HAVE_CUDA for now. No behaviour change.
Adds HIP runtime (hip_runtime.c) and hipFile GDS backend (gpu_io_hipfile.c) plus HIP kernels (utilities-gpu.hip). configure: --with-hip, --with-hipfile, --with-gpu-direct-backend=hipfile. hipFile needs ROCm 7.2.x+ and is opt-in.

Depends on #539.
New files:
configure: --with-hip, --with-hipfile, --with-gpu-direct-backend=hipfile.
Makefile.am: .hip.o rule, HIP source list.
hipFile needs ROCm 7.2.x+, local NVMe, ext4/xfs, kernel P2PDMA.
