Adjust build to allow running from forks or feature branches (#2998)

Make it possible to run build on feature branches by adding a flag that
can be used to select whether the build output will be uploaded to the
R2 artifacts bucket or kept only as build artifact on GH. The latter is
also used for 3rd party repos, allowing builds in forked repositories.

Feature builds are using Unix timestamp as the dev version suffix. This
makes them easily distiguishable, yet it makes them appear to be newer
than standard daily dev version builds when compared by AwesomeVersion.
