opencl : alignment size converted from bits to bytes (#7090)
* opencl alignment size should be converted from bits to bytes
Reference: https://registry.khronos.org/OpenCL/specs/3.0-unified/html/OpenCL_API.html#CL_DEVICE_MEM_BASE_ADDR_ALIGN
> Alignment requirement (in bits) for sub-buffer offsets.
* Update ggml-opencl.cpp for readability using division instead of shift
