tcpmv2: dpm: Convert dpm_run to a 1st class SM framework
This CL adds a type-c state machine framework for the Device Policy
Manager (dpm) layer of USB-PD. This CL is focused just on adding the
state machine policy and minimizing any changes in the existing DPM
support functions.
Because the DPM is no longer being called directly from the PE layer,
an interlock mechanism is used to control when the DPM state machine
will take any actions.
This CL also renames include/usb_pd_dpm.h to include/usb_pd_dpm_sm.h
to be consistent with include file naming for the other TCPMv2 layer
state machine include files.
BUG=b:194504052
BRANCH=none
TEST=Verified that mode entry/exit is successful for DP, TBT, and
USB4 on Voxel.
ectool typeccontrol <port> 0 -> exit mode
ectool typeccontrol <port> 2 0 -> DP
ectool typeccontrol <port> 2 1 -> TBT
ectool typeccontrol <port> 2 2 -> USB4
