rusticl/kernel: explicitly set rounding modes

Since dbbf566588c ("aco,ac/llvm,radeonsi: lower f2f16 to f2f16_rtz in nir")
radeonsi behavior changed and some of the core fp16 ops broke as a result.

We should explicitly specify the rounding mode until we add an gallium API
for drivers to advertize what they prefer.
