Thanks @dancgr, LGTM!

There is no harm in adding these intrinsics, but it is worth pointing out that our downstream compiler does not have explicit intrinsics for the immediate forms because:

- There are no specific C/C++ intrinsics that require the operand to be an immediate. That means using the immediate form is purely an optimisation of the general ((unpredicated) vector, vector) case.
- We can use a pattern to match e.g. the `AArch64dup (SVELogicalImm32 i64:$imm)` and emit the immediate-form of the instruction.
