feat(dev-infra): add release command for setting NPM dist tag (#38656)

Introduces a new command for `ng-dev release`, so that the NPM
dist tag can be set for all configured NPM packages. This command
can be useful in case a manual tag needs to be set, but it is
primarily used by the release tooling when a new stable version
is cut, and when the previous patch branch needs to be set as LTS
version through a `v{major}-lts` dist tag.

It is necessary to have this as a command so that the release tool
can execute it for old branches where other packages might have been
configured. This is similar to the separate `ng-dev build` command
that we created.

Note that we also added logic for spawning a process conveniently
with different "console output" modes. This will be useful for
other command invocations in the release tool and it's generally
better than directly using native `child_process` as that one doesn't
log to the dev-infra debug log file.
