bump crengine: LI and CITE fixes are now the defaults (#3976)

Books previously opened (that have a metadata.lua, whether with
highlights or not, but because they all have a last_xpointer that
points to the current page, that can be broken too by the changes)
will continue to have the old wrong behaviour, so they won't be
impacted by the breaking changes.
Update cre_dom_version code to use the new functions from cre.cpp.
Remove these Workarounds from Style tweaks.
