hexagon: tiling, tracing and optimizations for unary ops (#25474)

* hexagon: tile wide rows in pointwise unary ops to avoid VTCM overflow

* unary: reject permuted tensors for now (not used by models)

* hex-unary: replace divs with fastdiv

* hex-unary: add vtcm layout and host computed kernel params

* hex-unary: move fastdiv init into kernel params

* hex-unary: add specialized thread functions to improve generated code

* hex-unary: tracing instrumentation for unary ops

* hex-unary: factor out hvx kernels, streamline and remove more duplication

* ggml-hexagon: fix std::min collision with Windows min macro

* hex-cmake: make lto build happy
