  [MLIR] Legalize certain `vector.transfer_read` ops of scalable vectors

THis patch add a transform  of `transfer_read` operation to change the
vector type to one that can be mapped to an LLVM type. This is done by
collapsing trailing dimensions so we obtain a vector type with a single
scalable dimension in the rightmost position.
