nir: Handle fp16 rounding modes at nir_type_conversion_op
nir_type_conversion enables new operations to handle rounding modes to
convert to fp16 values. Two new opcodes are enabled nir_op_f2f16_rtne
and nir_op_f2f16_rtz.
The undefined behaviour doesn't has any effect and uses the original
nir_op_f2f16 operation.
v2: Indentation fixed (Jason Ekstrand)
v3: Use explicit case for undefined rounding and assert if
rounding mode is used for non 16-bit float conversions
(Jason Ekstrand)
