    c++: install cp-trait.def as part of plugin headers [PR107136]
    
    This is apparently needed since we include cp-trait.def from cp-tree.h
    (in order to define the cp_trait_kind enum), as with operators.def.
    
            PR c++/107136
    
    gcc/cp/ChangeLog:
    
            * Make-lang.in (CP_PLUGIN_HEADERS): Add cp-trait.def.
