Arm backend: Stop removing kwargs in quantizer

[Erik-Lundell]

torchao now allows non-tensor kwargs when quantizing. Currently, I am not aware of any tensor kwargs so it is probably better to crash and handle it if we run into them instead of silently not quantizing them.

Add a test to make sure kwargs actually do survive quantization.
