Package license removal [RUN AS-IF-FOSS]

What does this MR do?

Removed package from licensing allowing any user to use the packages feature.

A few considerations:

• in some tests the description was changed to something like "without the need for a license", this was done in order to keep the indentation of the tests and avoid making the MR too confusing to review by causing too many diffs.
• as the the package code is still inside /ee, some places now check for Gitlab.ee? instead of the license to make sure things still work in core when /ee is not present.
