build: upload release packages as job artifacts for PRs

[devversion]

Upload release packages as job artifacts for PRs. This allows
us to easily check out changes from a PR locally, without having
to manually check-out the branch, and building the release output.

[devversion]

Example artifacts have been uploaded for this PR here. Credits for this idea go to @gkalpak. This has been implemented in angular/angular too. We should add some docs for this too, if we decide to merge it.

I'm unsure about costs for CircleCI. Maybe @josephperrott knows more?

[gkalpak]

🚀

FYI, we have some docs about it here.

_{FWIW, here is the original discussion about cost (internal link)}

[googlebot]

All (the pull request submitter and all commit authors) CLAs are signed, but one or more commits were authored or co-authored by someone other than the pull request submitter.

We need to confirm that all authors are ok with their commits being contributed to this project. Please have them confirm that by leaving a comment that contains only @googlebot I consent. in this pull request.

Note to project maintainer: There may be cases where the author cannot leave a comment, or the comment is not properly detected as consent. In those cases, you can manually confirm consent of the commit author(s), and set the cla label to yes (if enabled on your project).

ℹ️ Googlers: Go here for more info.

Thanks @gkalpak. I've used the docs you wrote on framework (with adjustments for this repo). Also thanks for linking the discussion about the costs of using job artifacts.

I think in the future we can have the scripts and docs shared in the dev-infra package. Created DEV-62

LGTM

A Googler has manually verified that the CLAs look good.

(Googler, please make sure the reason for overriding the CLA status is clearly documented in these comments.)

@devversion can to file an issue for devinfra to share a single script for all repos for this?

[devversion]

@jelbourn Yeah, already did this. See: DEV-62
