TCPMv2: Refactor DP mode to use a state machine
Refactor the DP alt mode handling to use a state machine
to process the commands, ACKs and NAKs.
Also add states to handle detecting a NAK on a DP mode enter command,
and attempt to exit the mode and then retry.
When a partner enters alt mode (e.g a monitor with DP alt mode), and
the EC is reset or goes into recovery mode, the new negotiation will
fail because the command to enter alt mode when the partner is already
in that mode will fail with a NAK.
BUG=b:159073520
TEST=Tested on duffy with a type-C monitor.
BRANCH=none
