Add basic test that shares a VM from one app to another

This test consist of 2 apps:
* MicrodroidTestApp - test driver
* MicrodroidVmShareApp - helper app that exposes a service that
  MicrodroidTestApp binds to.

The test orchestarted by MicrodroidTestApp consists of the following:

1. MicrodroidTestApp starts & stops a VM
2. MicrodroidTestApp creates a descriptor of that VM
3. MicrodroidTestApp binds to service in MicrodroidVmShareApp
4. MicrodroidTestApp sends the descriptor to MicrodroidVmShareApp
5. MicrodroidVmShareApp starts a VM from that descriptor, and connects
   to the vsock service exposed by the VM.
6. MicrodroidVmShareApp shares a binder interface for MicrodroidTestApp
   to interact with the service exposed by the MicrodroidVmShareApp VM.
7. MicrodroidTestApp uses that binder to assert on the VM.

This change adds the scaffolding and a basic test, more involved test
(e.g. with trusted storage) will be added in the follow up changes.
