releng: add creation of DMG package for mac M1

We are learning about this as we go. Here are sources of information
that were useful:

EF documentation:
https://wiki.eclipse.org/IT_Infrastructure_Doc#macOS_DMG_file_creation

Bug (previous effort):
https://bugs.eclipse.org/bugs/show_bug.cgi?id=578792

EPP example:
https://github.com/eclipse-packaging/packages/blob/b25cbdb07e72c73c2f932ae9406d50f6e8707eca/releng/org.eclipse.epp.config/parent/product/pom.xml#L120-L152

Also, required infrastructure:  add "org.eclipse.equinox.executable" to
the "tracing.product" file and similar for legacy products. Add the
"environment" for "macosx/aarch64" in root pom.xml.

[added] Create .dmg package for mac M1 (aarch64 and x86_64)
