Andreas Kling b583fd3b79 LibWeb: Skip repaint for visual context-only style changes 
Let style changes that only rebuild compatible accumulated visual
contexts avoid marking the display list dirty. This lets transform
and nonzero opacity updates send visual context tree updates without
recording a new display list.

Keep repainting changes that affect display-list contents or can change
visual context tree compatibility, including zero-crossing opacity,
transform invertibility crossings, background-attachment, clipping,
mix-blend-mode, and perspective. Schedule accumulated visual context
updates for animations independently of repaint so animated
transform/effect updates keep reaching the document.

Cover compatible visual context reuse, incompatible tree shapes, and the
display-list invalidation cases with focused LibWeb tests.
