TCPMv2: Define typeccontrol host command
For now, just support exiting the entered mode, if that mode happens to
be DisplayPort (getting TBT3 and USB4 to work correctly will require
some more work). Support this command in ectool.
BUG=b:168030639
TEST=ectool typeccontrol 0 1; observe DP Exit Mode exchange in PD trace
BRANCH=none
