module adapter: pass config size to module for ipc4

IPC4 SOF_IPC4_MOD_INIT_INSTANCE provides size of the configuration
blob for the module. This size should be passed down to module adapter
and forwarded to module.
There are several reasons for using it:
- consistency with IPC3 flow;
- need for passing the size to IADK loadable modules;
- possibility to graceful failure in case of configuration inconsistency.
