[UnifiedPDF] Prepare for sharing some PDF page painting data with async
rendering
https://bugs.webkit.org/show_bug.cgi?id=269270
rdar://122851341
Reviewed by Tim Horton.
Async PDF painting will need to be able to paint the set of pages that intersect
with a given clipRect (corresponding to a tile) in m_contentLayer coordinates,
in a way that does not use the thread-unsafe PDFDocumentLayout.
So make a little data structure, `PDFPageCoverage` to hold enough information
about
the set of pages that intersect the given rect, and their geometry.
`UnifiedPDFPlugin::pageCoverageForRect()` computes this data, and
`UnifiedPDFPlugin::paintPDFContent()`
is updated to use it.
Also pass a clipRect to `UnifiedPDFPlugin::paintPDFOverlays()` to avoid filling
a rect outside the clip,
and make the code easier to read.
