target/riscv: rvv-1.0: Add ELEN checks for widening and narrowing instructions
SEW has the limitation which cannot exceed ELEN. Widening instructions have a destination group with EEW = 2*SEW and narrowing instructions have a source operand with EEW = 2*SEW. Both of the instructions have the limitation of: 2*SEW <= ELEN.
