January 2025 Update (#1036)

* code changes for december update (not working yet)

* Changes to support up to ggml-org/llama.cpp@d408bb9

* Updated to latest llama.cpp binaries, this works on Windows CPU but needs more changes for other backends

* Updated to latest deps, fixed kernel memory failing to load

* Copy missing Mac flibraries libggml-base and libggml-cpu

* Removed any mention of AVX in MacOS loading

* Added file copying for some more targets (still missing macos)

* Updated to latest set of binaries

* Fixed copy path for CUDA12 DLLs

* Compatibility with llama.cpp backend split (PR #10256) on all platforms

* Restore original comment

* Update the dependency loader for ggml-metal and ggml-blas

* Update the runtime targets for ggml-metal and ggml-blas

* Add CPU backend (fallback) dependency for the GPU backends

* Fix icons for the nuget backends

* Update nuspec files for the GPU backends

* Update BinaryReleaseId

* Update nuspec for CPU & OSX

* Update CPU nuspec to use noavx folder

* Update Runtime.targets to use noavx folder

* Update BinaryReleaseId

* CUDA & Vulkan native libraries now correctly store the detected or user defined AVX level
