No error in CFE when `call` getter of an extension is invoked

[sgrekhov]

This issue derieved from the test mentioned in #55803 (comment). The following code produces an error in the analyzer but works in CFE

class BEC {}

extension on BEC {
  int Function(int) get call => (int x) => x;
}

main() {
  BEC()(42); // Analyzer error: The expression doesn't evaluate to a function, so it can't be invoked. invocation_of_non_function_expression
}

According to the #55803 (comment) there should be an error in the CFE as well.
