[UnifiedPDF] Can't click-drag the scrollbar
https://bugs.webkit.org/show_bug.cgi?id=271115

Reviewed by Abrar Rahman Protyasha.
For mouse interaction with the PDFPlugin's scrollbars to work,
`EventHandler::enclosingScrollableArea()`
has to be able to find the plugin node's ScrollableArea. Add an easy way to get
to the ScrollableArea
from RenderEmbeddedObject, which calls through the PluginView. Replace the odd
code in `startKeyboardScrollAnimationOnPlugin()`
with this cleaner code.
Oddly that broke keyboard scrolling, which is fixed by implementing
`scrollAnimatorEnabled()` in
PDFPluginBase to return true.
Also implement `PDFPluginBase::enclosingScrollableArea()`; this isn't called on
macOS at this point, but
is implemented for completeness.
