This allows disabling parallelism in ngcc if desired, which is mainly useful for debugging. The implementation creates the flag and passes its value to mainNgcc. No tests are added since the feature mainly exists already - ngcc supports both parallel and serial execution. This commit only allows switching the flag via the commandline. PR Close #33192
