use P2Exporter for org.bndtools.p2

[chrisrueger]

Closes #5156

first draft of using https://bnd.bndtools.org/plugins/p2export.html for bnd itself the goal is to replace the veery old way of building the bnd p2 artifact and use bnd itself.

Importantly this solves the issue to use SHA-256 for checksum in addition to md5 to solve the Eclipse warning like "The digest algorithms (md5) used to verify ...jar have severely compromised security. Please report this concern to the artifact provider."

TODOs

• need to add ecf
• and verify it matches the current p2 artifact.

Will look in to the erro

This error was solved by disabling maven-release , buildrepo and releaserepo for this bund:

-maven-release: 
-buildrepo: 
-releaserepo: 

since this bundle should not go to a maven repo

Question @chrisrueger I was/am looking to do p2 repo builds with bndtools workspaces/projects. Are things in place (snapshot I assume) that would currently allow that? Or are there additional changes/fixes/updates that are required (that you know of, of course). I'm just trying to plan my efforts (and required bndtools versions). Thanksinadvance.

[chrisrueger]

@scottslewis I am new to this whole p2 topic (besides being a user / consumer when installing stuff into Eclipse) and this PR here is my first adventure.

I based this PR on the following test(data) https://github.com/bndtools/bnd/tree/master/biz.aQute.repository/testdata/p2-publish/ws-1/p1 (testcase) which matches the description in https://bnd.bndtools.org/plugins/p2export.html I think is a good example of the parts required to do P2 Exports with bnd.

UPDATE: This stuff should already work with the released bnd 7.1.0

Installing locally I get the following problem with the ECF feature. Need to find out why.

Cannot complete the install because one or more required items could not be found.
  Software being installed: Bndtools ECF Remote Services 7.2.0.202508261458-SNAPSHOT (bndtools.ecf.feature.feature.group 7.2.0.202508261458-SNAPSHOT)
  Missing requirement: Bndtools ECF Remote Services 7.2.0.202508261458-SNAPSHOT (bndtools.ecf.feature.feature.group 7.2.0.202508261458-SNAPSHOT) requires 'org.eclipse.equinox.p2.iu; org.eclipse.ecf.core.feature.feature.group [7.2.0.202508261458-SNAPSHOT,7.2.0.202508261458-SNAPSHOT]' but it could not be found

UPDATE:
It looks like the reason is that import feature like org.eclipse.ecf.core.feature.feature.group use the same SNAPSHOT version as my own artifact, which does not exist. Will investigate what to do

Closing this PR because it was superseeded by #6808 which is the same content but inside bndtools organization.
