Use more unique names for blink core TestCase classes

It is fairly common to have a help struct with test data and a fair
portion of the code call that struct TestCase and put it in a fairly
global namespace. In jumbo builds those structs will collide so this
patch renames them to more specific names such as
MediaQuerySetTestCase or SizesCalcTestCase.
