apply different quality of life improvements to the shadow css unit tests: - refactor the tests so that they are nicely divided in multiple files in a logical manner instead of having most of them all in a single big file - remove the css normalization logic inconsistently used throughout the tests, which causes tests to be inconsistent and it also introduced unintuitive checks - provide a shared shim utility function (instead of re-defining it multiple times) - add a `toEqualCss` matcher that can be used in the tests in order to match css strings without caring about spacing and indentation PR Close #48443
