  [UnifiedPDF] Context menu events should update selections

Reviewed by Tim Horton and Simon Fraser.

This patch introduces support for selection updates based on context
menu events (right click or ctrl-click).

It does so by adding some logic for context menu events that shortcuts
the rest of our selection tracking operation. Specifically, we call into
updateCurrentSelectionForContextMenuEventIfNeeded, which generates a text
selection for the word under which the click is produced, unless of
course the click location already intersects with an existing selection.

Furthermore, we add a lastHandledEventWasContextMenuEvent flag to our
selection tracking data, which we consult when determining whether
selections should be painted with an active or inactive appearance. This
is relevant because interacting with context menus causes selections to
go inactive in shipping macOS.

Finally, we make some drive-by fixes where we opt to pass enumeration
values such as WebEventType by value and not as const references, since
they are POD types.
