[AArch64] Use pattern to select bf16 fpextend (#137212)
Currently bf16 fpextend is lowered to a vector shift. Instead leave it
as fpextend and have an instruction selection pattern which selects to a
shift later. Doing this means that DAGCombiner patterns for fpextend
will be applied, leading to better codegen. It also means that in some
situations we use a mov instruction where we previously have a dup
instruction, but I don't think this makes any difference.
