Scott 2784e922ae pd: Changes to USB PD state machine for SRC DTS mode ...

In order to make pass through charging safe, there must be a mechanism
to signal the CHG port manager that Vbus is available and in a steady
state. When a typec only charger is used for the CHG port, then it's
steady state is SRC_DISCOVERY. Need a way to differentiate the TypeC
only charger from a USB PD charger that's also going through
SNK_DISCOVERY.

In addition, to allow a DTS device to support PD messaging, can't
stay in SRC_ACCESSORY state. This CL makes a modification to the
USB PD state machine so that if a debug accessory is detected and
CONFIG_USB_PD_DTS is defined, then the state machine will advance to
SRC_STARTUP and prepare for messages similar to when a UFP attach
is detected.

BUG=b:35586526
BRANCH=servo
TEST=Manual Built for both Plankton and Reef, verified that Reef
connects as both SNK and SRC.
