RFR: 8352159: RISC-V: add more zfa support [v2]

[Hamlin Li]

> Hi,
> Can you help to review this patch?
> 
> Previously in https://github.com/openjdk/jdk/pull/23844, `loadConH` is implemented only with `flh`, but `fli_h` should be more efficient if Zfa is supported; min/max for HF could use fmin/maxm.h instead too.

> Thanks!
