module_adapter: Allocate data buffers from MMU shared heap

The security reqirements assume that the non-privileged
modules data and code should be protected from other non-privileged
modules access. The audio data could be accessible.
This PR allocates audio data buffer from shared memory heap.

This change is effective only when CONFIG_USERSPACE=y.
