Support f16->f32 copy.
Support f16->f16 and f32->f32 unary ops.
Support all combinations of f16/f32 for src0/src1/dst for add/sub/mul/div.
Another engineer at NVIDIA was writing some code using the ggml api, and quickly ran into some cases we didn't support in the Vulkan backend. He wanted to do an add with types f32=f32+f16. When that didn't work, trying to convert from f16->f32 also didn't work due to a missing copy variant. And relu with f16 was also unsupported.
