PR Summary

• Refactoring ActiveDataProvider.php
  The code was simplified by removing unnecessary lines that were previously being used to count total items. This helps in making the program run faster and more efficiently.
• Optimization in ArrayDataProvider.php
  The pagination process, which controls how items are displayed over several pages, has been improved. It now uses a more efficient method for handling the distribution of items.
• Improving Conditionals in BaseDataProvider.php
  The process to check whether total count of items is established was restructured. This design tweak furthers optimization, by making the system smarter in how it handles counts of items.
• Code Cleanup in SqlDataProvider.php
  Similar to the changes in ActiveDataProvider, redundant lines were removed, simplifying the process of gathering the total count of items. This contributes to overall efficiency in the SQL data handling process.

@lav45 how about #20060?

[lav45]

@samdark This is a crutch that is long overdue for removal.

Take a look at the changes in tests/framework/data/ActiveDataProviderTest.php

Would you please add a line for CHANGELOG?
