platform/chrome: cros_ec_typec: Update partner altmode active

Browse Source 
Mux configuration is often the final piece of mode entry and can be used
to determine whether a partner altmode is active. When mux configuration
is done, use the active port altmode's SVID to set the partner active
field for all partner alt modes.
