…yle and math-script-level , a=testonly

Automatic update from web-platform-tests
Add new tests for CSS properties math-style and math-script-level  (#17100)

* Add tests for new CSS property math-style.

* Add tests for CSS property math-script-level

* Add tests using scaling factors from the MATH table.

* Improve coverage of math-script-level-004:
- Test scaling without MATH font.
- Test scaling up and down.
- Test all transitions between levels -3, -1, 0, 1, 2, 3, 5.

* Add tests to check issue #3739 and interaction with script-level.

* Add a tentative reftest to check how math-script-level and font-family interacts on font-size change. This is related to w3c/csswg-drafts#3906
