Add support for MAVEN_PROJECTBASEDIR substitution (backport of MNG-8598)

[mguillem]

This backports the changes from [MNG-8598] without integration tests as the setup for them doesn't exist here.

See #2194, #10140

Following this checklist to help us incorporate your
contribution quickly and easily:

• Your pull request should address just one issue, without pulling in other changes.
• Write a pull request description that is detailed enough to understand what the pull request does, how, and why.
• Each commit in the pull request should have a meaningful subject line and body.
  Note that commits might be squashed by a maintainer on merge.
• Write unit tests that match behavioral changes, where the tests fail if the changes to the runtime are not applied.
  This may not always be possible but is a best-practice.
• Run mvn verify to make sure basic checks pass.
  A more thorough check will be performed on your pull request automatically.
• You have run the Core IT successfully.

If your pull request is about ~20 lines of code you don't need to sign an

@gnodet can you provide some information on the failed tests? As far as I can see it, they don't belong to the target branch therefore I don't understand why they are executed.
