This sort of setup (P2P PWE3) should pass state of the PE-CE interface
by default.
One of our setups:

l2vpn
 xconnect group layer2_504
  p2p layer2_504
   interface GigabitEthernet0/1/0/3.504
   neighbor 10.123.130.1 pw-id 504

#sh l2vpn xconnect group layer2_504
Tue Oct 30 07:50:59.164 NZDT
Legend: ST = State, UP = Up, DN = Down, AD = Admin Down, UR = Unresolved,
        SB = Standby, SR = Standby Ready, (PP) = Partially Programmed

XConnect                   Segment 1                       Segment 2
Group      Name       ST   Description            ST       Description
           ST
------------------------   -----------------------------
-----------------------------
layer2_504 layer2_504 UP   Gi0/1/0/3.504          UP
10.123.130.1    504    UP
----------------------------------------------------------------------------------------

if I take down the interface the PWE2 part goes down as well,
signalling the other end to take the physical port down as well.

#sh l2vpn xconnect group layer2_504

Legend: ST = State, UP = Up, DN = Down, AD = Admin Down, UR = Unresolved,
        SB = Standby, SR = Standby Ready, (PP) = Partially Programmed

XConnect                   Segment 1                       Segment 2
Group      Name       ST   Description            ST       Description
           ST
------------------------   -----------------------------
-----------------------------
layer2_504 layer2_504 DN   Gi0/1/0/3.504          AD
10.123.130.1    504    DN
----------------------------------------------------------------------------------------
