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.

On GitHub CI, there is a very strange error while downloading the POM,
which does not occur locally. Maybe this is due to the usage of
inline XML tags inside a CDATA section in the 'description' tag text.
The default mode removes the description.

There is a warning because 'asm-renamed' uses
<version>${asm.version}</version> in its artifact descriptor instead of
a fixed version. but as long as Maven still permits it, let us use it
this way. Flatten Maven plugin replaces it by a resolved number anyway
for the dependency-reduced POM.

This means that instead of a system-scoped dependency we now have a
regular one.

The 'libx' module also downloads binary and source JARs redundantly into
the libraries directory in order to be found there by other scripts and
tests.
