* ggml-cpu: add F16 input to the FWHT The CPU FWHT accepts F32 input only. This change makes the source type a template parameter. The CPU path now accepts F16 input and F32 input. The CPU MUL_MAT reference now converts an F16 src1 to F32. It does this when the caller sets the Hadamard hint. No backend has an F16 FWHT kernel yet. The test cases come with the backend changes that add one. * ggml-cpu: assert the F16 FWHT input path, and use the bulk converter Address review feedback. The F16 branch writes plain floats into wdata, which is only correct when vec_dot_type is F32. That invariant held because supports_op only accepts an F16 src1 for the Hadamard hint with F32 src0 and dst, but nothing enforced it. Assert it next to the existing src1 type check so widening supports_op cannot silently break the write. Replace the hand-rolled conversion loop with ggml_cpu_fp16_to_fp32.
