Add inputs.delocate-wheel to build_wheels_macos.yaml (#5107)

Give clients a way to disable wheel delocation.

This step is only run on macOS, so there's no equivalent change

is an example run using a forked copy of this file (see
pytorch/executorch@aca550b).
It successfully skips the "Install delocate-wheel" and "Delocate wheel"
steps.

While on the testing for this PR, both of those steps run by default:
