Allow overriding mix-blend-mode in ComputedStyle
rdar://188964338
https://bugs.webkit.org/show_bug.cgi?id=326031
Reviewed by Simon Fraser.
This patch adds the ability to override mix-blend-mode in ComputedStyle,
such that the used value can be different from the computed value. The
overriden value is stored in overrideBlendMode in NonInheritedRareData,
and can be set using setOverrideBlendMode. The used value is exposed
through ComputedStyle::usedBlendMode, and rendering code were changed
to use this instead of ComputedStyle::blendMode.
Tested by existing test suite.
