Import wrappers were only logged if logging was enabled during
compilation. If the profiler is enabled later, and regular wasm code is
logged via {NativeModule::LogWasmCodes}, the import wrappers were
missing.
This CL fixes the long-standing TODO, and adds tests which triggered
that code path. Those tests were hanging before because the expected
functions did never appear in the profile.

Drive-by: If {WasmEngine::LogOutstandingCodesForIsolate} detects that
code logging is disabled by now, it should still clear the {code_to_log}
vector.
