test: mark tests with Allure steps and attachments

[xpyctumo]

Issue

Closes nothing :)

But here continued work on the markup that was started in #2778

Allure metadata checklist

To ensure that the tests are rich, I suggest dividing the list into folders with *.spec.ts files, inside which we will need to add Allure data, for example, step() or parameter()

• ast
• benchmarks
• cli
• error
• fmt
• func
• generator
• grammar
• imports
• optimizer
• pipeline
• test
• server
• storage
• types
• utils
• vfs

Other places will be in other PR, for example test contains more 50 *.spec.ts files
