Only single native image is built at a time

[Akirathan]

Pull Request Description

#10783 introduced another definition of a buildnativeimage task. Since that time, our CI is transiently failing on out of memory error. This PR ensures that there can be just a single buildNativeImage task running at a time.

Important Notes

Manually tested by running

sbt:enso> all engine-runner/buildNativeImage project-manager/buildNativeImage

And looking at spawn subprocesses. On develop, I have two native-image processes, on this PR, there is just a single one.

What a black magic or sbt trick! This is completely different fix than I was envisioning. If it does the job, then great, however.
