usb_pd: Sending Thunderbolts-compatible host notification
Sending the following information to the host in cros_ec_usb_pd_control
command to configure thunderbolt compat mode:
1. TBT flag - Contains information about:
a. Retimer (Present/Absent)
b. Thunderbolt-compatible adapter (Type-C/ Legacy TBT adapter)
c. Thunderbolt-compatible type (Optical/Non-optical)
d. Active link training (Uni/bi-directional communication)
2. Cable speed (USB3.1 Gen1 Cable / 10 Gbps / 10 Gbps and 20 Gbps)
3. Cable rounded support (3rd Gen Non-Rounded TBT/
3rd & 4th Gen Rounded and Non-Rounded TBT)
BUG=b:140644242
BRANCH=None
TEST=Verfied on the tglrvp-u CPU console using "ectool usbpd" command,
able to get the information
