  -----------
  [AArch64][GlobalISel] Support returned argument with multiple registers

The call lowering code assumed that a returned argument could only
consist of one register. Pass an ArrayRef<Register> instead of
Register to make sure that all parts get assigned.

Fixes https://github.com/llvm/llvm-project/issues/53315.
