audio: Create ModulePrimary and ModuleStub

Make 'Module' more abstract by moving stream creation
methods to more concrete 'ModulePrimary' and 'ModuleStub'.
'ModulePrimary' is now closer to the CF primary module:
it was stripped off USB devices from its configuration,
these got moved to 'ModuleUsb', and got rid of BT A2DP
and LE interfaces, these will be on 'ModuleBluetooth'.
Note that 'ModulePrimary' still uses stub streams, this
will be changed in subsequent patches.

'ModuleStub' is what 'Module' used to be, just a module
for improving test coverage. It includes simulation of
offload streams and dummy BT objects.
