TCMPV2: Add USB PD power button support in S0/S0ix/S3 states
Currently a USB PD power button can only be used wake a device which is
shutdown. To account for devices which use a USB PD power button and
cannot enable a HID interface, this CL adds USB PD power button support
to Suspend and On power states. When a device is either suspended or on,
a short USB PD power button press will simulate a 500ms power button
press and a long USB PD power button press will shutdown the device.
BUG=b:236022894
TEST=make try_build_boards, make runhosttests and zmake test
test-drivers. Also working interactively with a dock that supports
sending alerts on button presses.
BRANCH=None
