Add PortConfig parameter

Browse source 
Add a new PortConfig parameter to configure ports of elements that
are marked with the SPA_NODE_FLAG_*_PORT_CONFIG. This is used to
configure the operation of the audioconver/audioadapter nodes and
how it should convert the internal format. We want to use the
Profile parameter only for cases where there is an enumeration of
values, like with device configuration.

Add unit tests for audioconvert and adapter to check if they handle
PortConfig correctly.

Make the media session use the PortConfig to dynamically configure
the device nodes.

Remove audio-dsp, it is not used anymore and can/should be implemented
with a simple audioconvert spa node now and some PortConfig.
