Summary Remove legacy MathML pixel test roots.xhtml

LayoutTests/mathml/presentation/roots.xhtml is the only remaining pixel test from the legacy MathML implementations in WebKit (before 2016). - This test is really dependent on the system font used, which make it confusing and less robust. - It contains a lot of mathematical constructions with radicals, but it's difficult to understand what they verify exactly when something breaks (compared to the more modern tests like reftest or testharness.js). - It breaks quite frequently, and we generally just update the text expectation for the render tree without trying to understand more (the screenshots are often out-of-date). Consequently it is causing more harm than good, so let's just remove it.
