[Task]: Build RC and non-RC wheels in parallel.

### What happened?

code path: https://github.com/apache/beam/blob/master/.github/workflows/build_wheels.yml

There is exactly same steps "Build Wheel" and "Build RC wheels", both run the same command and produce same wheels with different naming:

```

Example run:

https://github.com/apache/beam/actions/runs/5467460207/jobs/9953842597

This becomes extremely time consuming as linux-aarch64 wheels costs 2.5 h to run, then the workflow costs >5 h to run.

Read .github/workflows/build_wheels.yml and compare the "Build Wheel" and "Build RC wheels" steps, then inspect the linked example run to understand their dependencies. Done means RC and non-RC wheel builds run in parallel, both produce the expected wheels, and the workflow completes without breaking its existing outputs.
