Support console input to VM
createVm accepts a new ParcelFileDescriptor which when set is used as
the console input in the VM. The `vm` tool sets this to stdin unless
explicitly specified via `--console-in`. This will be useful for
bringing up custom OSes.
Note that Java APIs for this is not added in this CL.
Bug: 263360203
Test: Start a vm using the `vm` tool. Type something. Then do `cat
/dev/console` in the VM. It shows the typed characters.
