[Build] Some Build Options/Definitions seems Missing in ggml-base

[QingtaoLi1]

It seems that in CMakeLists, ggml-base has very few compile options/definitions, but the source files which it includes rely on them.

For example, in ggml.c, this function void ggml_bf16_to_fp32_row(const ggml_bf16_t * x, float * y, int64_t n) checks __AVX512F__ and __AVX2__, but they are not defined during ggml-base compiling.

Is this a by-design behavior or a bug?

It's an artifact of when the CPU backend was moved to a different library, initially everything was together. It may still be useful if someone enables AVX in all sources via CFLAGS or similar, but normally the accelerated path won't be used. Still, it would be good to move the accelerated path of these functions to the CPU backend, although they are not used very often.
