Log Message:
-----------
[RISCV] Add rvv codegen support for vp.fpext.
This patch adds rvv codegen support for vp.fpext. The lowering of fp_round, vp.fptrunc, fp_extend and vp.fpext share most code so use a common lowering function to handle these four.
And this patch changes the intermediate cast from ISD::FP_EXTEND/ISD::FP_ROUND to the RVV VL version op RISCVISD::FP_EXTEND_VL and RISCVISD::FP_ROUND_VL for scalable vectors.
