Updating dependencies of modules in standard build to new versions of openide.util and openide.util.lookup

Merging with default, so we can use Jesse's 178260

Fixing old cross-API links of the form @JAVA/PROJECT@, now @org-netbeans-modules-java-project@.

#178009: dependencies on "higher" clusters are not permitted, even from tests.
Attempts to use e.g. java cluster from ide cluster tests can cause build-test-dist to fail in some cluster configs.
Removing illegal dependencies; in some cases they were unused, or the code using them could be easily excised.
In other cases, most of the test root was relying on an illegal dep, so just disabling that test root until it can be fixed.
Most useful would be a test utility in the ide cluster to create a generic "project" with no domain-specific behavior;
lots of tests seem to make a j2seproject just for the sake of having something open with some sample files,
for which the functionality of the j2seproject module is overkill and introduces performance and robustness penalties
(such as waiting for "scanning to finish" when the test does not even relate to Java source editing).
Also removing the performance pseudomodule from the BTD as it has various dependencies inapplicable to some configs;
better to factor it into utility modules according to domain, as was done for jellytools, and remove special treatment.

Merge with default after spec versions has been updated after release68 cloned

Incrementing spec. versions after 6.8.

Fixing invalid layers.
