Rename PageData to GenericXLogPageData

Browse Source 
In the PostgreSQL C type naming schema, the type PageData should be
what the pointer of type Page points to.  But in this case it's
actually an unrelated type local to generic_xlog.c.  Rename that to a
more specific name.  This makes room to possible add a PageData type
with the mentioned meaning, but this is not done here.
