[mlir][vector] VectorToSCF: Omit redundant out-of-bounds check

There was a bug in `TransferWriteNonPermutationLowering`, a pattern that extends the permutation map of a TransferWriteOp with leading transfer dimensions of size ones. These newly added transfer dimensions are always in-bounds, because the starting point of any dimension is in-bounds. VectorToSCF inserts out-of-bounds checks based on the "in_bounds" attribute and dims that are marked as out-of-bounds but that are actually always in-bounds lead to unnecessary "scf.if" ops.
