Move more classes to use WebLocalFrameBase from WebLocalFrameImpl.

These use cases do not require any further virtual methods to be declared in
WebLocalFrameBase - they simply call the existing Client() method.

This CL updates:
- AudioOutputDeviceClientImpl.cpp
- MediaKeysClientImpl.cpp
- WebPluginContainerImpl.cpp
