This change removes the project attachment support, and instead relies
on x-plugins being checked out under extra-plugins/x-plugins within an
elasticsearch checkout. The only real change, other than removing
unnecessary code, was to rename the license/core project because gradle
project substitution has a bug which causes it to try and use ES core as
the substitution. (Unfortunately this is not reproduceable with a simple
example, so I have not yet filed an issue with gradle).

In elastic/elasticsearchelastic/elasticsearch#14668, transitive dependencies were removed
from elasticsearch, and plugins now no longer get transitive deps
either. This commit fixes xplugins to remove transitive deps.

Currently, running any task while attached to elasticsearch will also
try to run that task in all elasticsearch projects. This change causes
x-plugins to be moved into a subproject when attached. It does this by
dynamically creating a fake root project, and making this root project
think it is attached to the existing attachments, along with x-plugins
itself.
This also fixes buildSrc so attachment to elasticsearch's buildSrc
actually works.
