Prepare main artifacts to be deployed via Maven, step 2

Prepare main artifacts to be deployed via Maven, step 2

This change affects the following modules:
  - aspectjmatcher
  - aspectjrt
  - aspectjtools
  - aspectjweaver
  - installer
  - asm-renamed

Set maven.deploy.skip=false in parent POM, i.e. Maven Deploy by default
will *not deploy anything. Only in the modules above, we change the
value to 'true' in order to deploy those artifacts.

This setting works for both snapshot repositories (GitHub Packages, soon
to be migrated to aspectj.dev in a separate PR) and release
repositories, i.e. in the future also for Maven Central.
