#12808: Optimize ClassCallMetaClass using Cython

---------------------------+------------------------------------------------
When a class {{{C}}} is an instance of {{{ClasscallMetaclass}}}, then for
any constructor call, the system currently looks for {{{__classcall__}}}
and {{{__classcall_private__}}} in {{{C}}}. This adds quite an overhead
and this could be cached, assuming no one modifies {{{C}}} (which seems
reasonable). Improving this speeds up, in particular, all call to the
constructor of a subclass of {{{UniqueRepresentation}}}, eg. many parents,
all categories...
