target/riscv: rvv:1.0: add translation-time nan-box helper function
* Add fp16 nan-box check generator function, if a 16-bit input is not
properly nanboxed, then the input is replaced with the default qnan.
* Add do_nanbox() helper function to utilize gen_check_nanbox_X() to
generate the NaN-boxed floating-point values based on SEW setting.
* Apply nanbox helper in opfvf_trans().
