Port from container::count() and length() to size()

This is a semantic patch using ClangTidyTransformator as in
qtbase/df9d882d41b741fef7c5beeddb0abe9d904443d8:

  auto QtContainerClass = anyOf(
      expr(hasType(cxxRecordDecl(isSameOrDerivedFrom(hasAnyName(classes))))).bind(o),
      expr(hasType(namedDecl(hasAnyName(<classes>)))).bind(o));
  makeRule(cxxMemberCallExpr(on(QtContainerClass),
                             callee(cxxMethodDecl(hasAnyName({"count", "length"),
                                                  parameterCountIs(0))))),
           changeTo(cat(access(o, cat("size"), "()"))),
           cat("use 'size()' instead of 'count()/length()'"))

a.k.a qt-port-to-std-compatible-api with config Scope: 'Container',
with the extended set of container classes recognized.
