 074944998d ggml : process data in smaller chunks in CUDA ggml_top_k() and ggml_argsort() to reduce temporary buffers memory usage (#24776) 
* ggml : process data in smaller chunks in CUDA ggml_top_k() implementation to reduce temporary buffers memory usage

* ggml : allocate tmp_dst only only once before the loop

* chore : whitespaces

Co-authored-by: Georgi Gerganov <ggerganov@gmail.com>

* ggml : use chunked processing in both CUDA CUB top-k and argsort implementations

* chore : separate argsort_f32_i32_cuda_bitonic() call from return statement

Co-authored-by: Johannes Gäßler <johannesg@5d6.de>

* chore : replace ternary operators with min/max
