TCPMv2: Store and report sink caps
Copy sink caps for later reference, and report them up to the AP in the
TYPEC_STATUS host command return. This also moves the location of the
DPM set for sink caps, to be symmetrical between source and sink inits.
Set the old unit tests to clear all DPM requests. New PE tests will
correctly handle our startup sequence, but the old tests may have
erratic behavior based on how many states run before the connection is
forced over to READY.
BRANCH=None
BUG=b:160009733,b:168862110
TEST=on drawcia, verify sink capabilities match those from PD traces
with several docks and dongles
