Make comparing FontCascades more efficient
https://bugs.webkit.org/show_bug.cgi?id=284583
rdar://141401574
Reviewed by Dan Glastonbury.
Call sites that currently compare FontCascade on two RenderStyles, which is
slow, now call
`RenderStyle::fontCascadeEqual()`, which checks to see if the m_inheritedData
and
m_inheritedData->fontData pointers are equal before doing the more expensive
comparison.
