ggml : avoid duplicating function calls using MIN/MAX macros (llama/5325)

* Avoid duplicating function calls when using MIN/MAX macros.

Since these copy "a" and "b" they ask the compiler to evaluate one of them twice. The compiler doesn't have a problem with removing the duplication in something like MAX(0, x + 2), but in some cases we're calling functions, and those calls just happen twice.
By explicitly evaluating at the expression we get smaller and faster code without duplicate calls. See ggml_rope_yarn_corr_dims in Compiler Explorer:

Code behaves exactly the same.

* Update ggml.c
