[LabKey CI] Eliminate DbCache use

[labkey-adam]

DbCache uses a very inefficient invalidation mechanism (the entire cache is cleared on insert, update, or delete of any row in any container). It's time to migrate uses to a more standard and efficient caching pattern, and eliminate this class.

• Migrate experiment runs cache DbCache -> DatabaseCache
• Migrate participant cache DbCache -> DatabaseCache
• Migrate StudyCache/QueryHelper DbCache -> DatabaseCache
• Add validation checking (old vs. new return values) and logging
• Fix failing tests and flagged validation problems
• Code review - @labkey-jeckels
• Merge with validation in place
• Fix tests (participant cache invalidation, delete specimen tables, bad insert button)
• Code review 2
• Merge test fixes
• Remove validation code and DbCache
• Code review 3
• Merge final PR
