Add a list of encoders to vkms_config and helper functions to add and
remove as many encoders as wanted.
For backwards compatibility, add one encoder to the default
configuration.
A future patch will allow to attach encoders and CRTCs, but for the
moment there are no changes in the way the output is configured.
