Normalize the way core does

After investigating the failing PHPUnit tests, it appears the issue is caused by unpredictable sequence order when configuration is saved without an orderby: key setting in the configuration's schema. As noted in the configuration schema documentation → , sequence data is preserved in the order it exists unless explicitly sorted.

My test uses PHP’s shuffle function to alter the sequence order artificially. Without an orderby: key setting in the schema for view displays, the order remains unpredictable, which is causing the PHPUnit tests to fail.

To test this, I added orderby: key or orderby: value to a local codebase in the following locations:

• views.schema.yml (Lines 95-97)
• views.data_types.schema.yml (Lines 62-94)
• views.schema.yml (Line 126)
• views.schema.yml (Line 131)

Additionally, please note that there is an open dependency array order issue: #3186905: Normalize config import → .

The Test will always fail unless we change the fixtures to remove sequences that aren't sorted, skip shuffling unsorted sequences, or some other way.

Setting as needs review to discuss what to do about this new PHPUnit test.

I'd also like some feedback on the overall approach.
