Implement GGML_CPU_ALL_VARIANTS for PowerPC (#14286)

Browse Source 
* Add PowerPC feature detection and scoring

* ggml-cpu: Implement GGML_CPU_ALL_VARIANTS for PowerPC

* ggml-cpu: Delay some initializations until function is called

When using GGML_BACKEND_DL=ON, these initializations might use
instructions that are not supported by the current CPU.
