sdbus++: async: client: fix client_t usage

When using the "Alternatively,..." syntax from calculator-client, we
end up with the compiler error:

```
example/gen/net/poettering/Calculator/client.hpp:149:40: error: ‘constexpr sdbusplus::client::net::poettering::details::Calculator<Proxy>::Calculator(sdbusplus::async::context&, Proxy) [with Proxy = sdbusplus::async::proxy_ns::proxy<true, true, false, false>]’ is private within this context
  149 |             std::forward<Args>(args)...)
```

Fix this by making the generated alias class a friend of the details
class, in addition to the client_t proxy. Add a compile test to ensure
this works.  Fix up a few whitespace alignment to better match
clang-format expectations.
