typecd: Add interface to control mode entry / exit

Create an interface which is used by typecd to check whether a device
supports mode entry and also triggers entry/exit into a particular mode.

The "prod" implementation of this consists of stubs for the time being.
This can be fleshed out with an actual implementation later.

Also add a simple unit test that utilizes a Mock with expectations to
make sure that the RunModeEntry code is correctly checking for mode
entry support and bailing if that is not available.
