libview: Add an option to show odd pages on the left in dual mode

Added a dual_even_left flag to EvView. When this flag is false, odd
pages appear left instead of even ones.

All the logic has been added to get_dual_even_left(). The patch is a bit
more involved because build_height_to_page() was computing
dual_even_left directly instead of calling get_dual_even_left(). Rather
than implementing the logic twice, we replaced its EvDocument argument
by its enclosing EvView in order to be able to call get_dual_even_left()
directly. This function was renamed into
ev_view_build_height_to_page_cache() to reflect it is now a view method.
