opencl: split ggml-opencl.cl into multiple files and cleanup (#12886)

* opencl: refactor - split the kernel files --------- Co-authored-by: Shangqing Gu <quic_shawngu@quicinc.com> * opencl: split more kernels into separate files * opencl: specify subgroup size instead of querying it * opencl: refine Adreno cl compiler version parsing * opencl: skip some kernels not used by Adreno on old compilers * opencl: refine logic for selecting Adreno kernels * opencl: refine Adreno cl compiler version * opencl: cleanup preprocessor for kernels * opencl: consider Adreno CL compiler on Windows * opencl: add final newline for `mul_mv_f16_f16.cl` --------- Co-authored-by: Shangqing Gu <quic_shawngu@quicinc.com>
