[RISCV] Rename BFloatVectors -> BF16Vectors in tablegen. NFC (#161469)

topperc · web-flow · commit 89ed5255b9ee · 2025-09-30T19:53:21.000-07:00
Part of this rename is taken from #161158, but applies it more consistently to more variables. I think using BF16 makes it easier to not confuse BFloat and Float when reading.
