perf: Enhance objects using constant sql queries count to get rid of N+1 queries

[Koc]

In our organization we operate a large amount of tables/views, so there are performance bottleneck here:

PERFORMANCE: Controller OCA\\Tables\\Controller\\Api1Controller::index executed 1883 queries in 20.1 seconds
PERFORMANCE: Controller OCA\\Tables\\Controller\\TableController::index executed 1887 queries in 16.6 seconds

• Replaced TableService::enhanceTable() in a loop with a single call of the enhanceTables()
• Replaced ViewService::enhanceView() in a loop with a single call of theenhanceViews()
• Added batch helpers in mappers/services and UserHelper for row/column counts, share counts and owner display names.

🖼️ Screenshots

Here profiler results for GET /apps/tables/table endpoint for 18 tables and 9 views:
