opencl: allow loading precompiled binary kernels from library (#23042)

* opencl: allow loading binary kernel * opencl: add libdl.h * ggml-backend-dl is in ggml, which depends backend libs, thus ggml-opencl cannot depend on ggml-backend-dl * add libdl.h to break cyclic dep * opencl: allow loading bin kernel lib * opencl: load `gemm_moe_mxfp4_f32_ns` from kernel lib if available * opencl: load q8_0 gemm from kernel lib * opencl: load q4_0 moe gemm from kernel lib * opencl: load q4_1 moe gemm from kernel lib * opencl: load q4_k moe gemm from kernel lib * opencl: always declare `get_adreno_bin_kernel_func_t` * opencl: rephrase message * opencl: fix for rebase * opencl: update doc
