ISSUE-47036: Remove support code for update.database.mod, ezattributes module and references to dbmanager.jar

update.database.mod is dead long time ago ezattributes module is unsupported also quite a while

Remove lots of code from dbsourcemanager to simplify it a lot.

Especially it removes the 3 slightly different ModelLoader sql variants per topic

This need MR !305 merged before which was still using API removed in here.

TODO

• (openbravo!305 (merged))
• rebased
• dbsm testsuite
• check all modules for using internal dbsm code
  • unsupported => no need to check
    • org.openbravo.retail.storeserver.synchronization, org.openbravo.replication.symmetricds, org.openbravo.ezattributes
  • NI
    • org.openbravo.reporting.tools
      • Check that it still compiles (it extends 4 dbsm classes)
      • No runtime check as no only code-removal in here
    • br.com.disoft.brazil.ce.core
      • Apparently forked via copy'n'paste the in-core SystemValidationTask into src/br/com/disoft/brazil/ce/core/validator/DisoftValidationTask.java
      • Forge published module
• check all dbsm usage in openbravo sourcecode
  • Relevant DatabaseValidator, SystemService only usage left is via dbsm ExportDatabase itself
  • junit test ClientExportImportTest
  • Note that 2 more usages were removed in 21Q2 already (https://issues.openbravo.com/view.php?id=29855) and (https://issues.openbravo.com/view.php?id=29853)
• OB-owned module marked still as supported but depends on already broken ezattributes
  • Library-To-Window
    • Module updated to Unsupported after checking with aza (was custom for a client, no longer useful/needed)
• try run
  • try-initial => both false positive (run was accidentally with release/21Q1 missing logo commit)
• try-retail run?
• mod-merged run?
• check/update/report dbmanager removal
