TCPMv2: Add common hpd->dp_atten converter
This CL adds a new file for UFP_D ports. The inclusion of this file is
controlled via a new config option CONFIG_USB_PD_ALT_MODE_UFP. Note
that this is not intended to be used with TCPMv1 UFP_D legacy devices.
The initial version of this file includes the hpd to usb pd
DP_ATTENTION message converter. The implementation follows the spec in
terms of both states and hpd event queueing rules.
BUG=b:175660576
BRANCH=None
TEST=Tested further down the CL stack. But verified that this CL fixes
the issue where too many hpd_irq messages are sent with gingerbread
which was causing a port part reset for chromebook ports.
