[VMVX] Added an implementation of fpowi in vm for vmvx backend (#24608)

We have found some models, which failed to compile to vmvx, due to a
missing conversion for math.fpowi.

This PR includes an implementation for this op, as well as an addition
of VM_ComplexArithmeticOp class, since fpowi has a float and int input.
This case was not covered by the VM_BinaryArithmeticOp class. However,
since we only found fpowi in models, which utilize a i64 const for the
exponent, the op was implemented in such a way that it only accepts i64
as an exponent. Due to this, it was not necessary to implement a
ComplexArithmeticOpConversion in
[MathToVM/Patterns.cpp](https://github.com/iree-org/iree/blob/main/compiler/src/iree/compiler/Dialect/VM/Conversion/MathToVM/Patterns.cpp).

I also expanded the tests in arithmetic_ops.mlir, to include a check for
vm.fpowi.f32.
