LibWeb: Join text clip paths before application in Skia painter

Browse source 
Each item in clip_paths represents a glyph run, and applying them as a
clip in intersection mode one by one results in an empty clip. Instead,
now all clip paths are joined and applied as a clip together.

This change fixes rendering of "background-clip: text" when an element
has more than one glyph run.

Fixed ref-test: Tests/LibWeb/Ref/css-background-clip-text.html
