IJPL-161967 IJent cleanup: make some IJent+WSL functions not suspendable

This is done just to make `IjentWslFileSystemApplicationActivity` look not so threatening. It's a lightweight class, but it used some suspend functions. In fact, these functions could be non-suspendable. They are not suspendable anymore.
