[VP][RISCV] Add a vp.load.ff intrinsic for fault only first load. (#128593)
There's been some interest in supporting early-exit loops recently.
https://discourse.llvm.org/t/rfc-supporting-more-early-exit-loops/84690
This patch was extracted from our downstream where we've been using it
in our vectorizer.
