This exception stack was once used by VMS, but isn't anymore.
No functional change.
Tested on x86_64-pc-linux-gnu, committed on trunk

* s-taprop-vms.adb (Get_Exc_Stack_Addr): Remove.
(Initialize_TCB): Remove Exc_Stack_Ptr initialization.
(Finalize_TCB): Remove its finalization.
(Initialize): Remove assignment of GET_Exc_Stack_Addr
* s-soflin.adb (NT_Exc_Stack): Remove
(Get_Exc_Stack_Addr_NT): Likewise.
(Get_Exc_Stack_Addr_Soft): Likewise.
* s-soflin.ads (Get_Exc_Stack_Addr_NT): Remove.
(Get_Exc_Stack_Addr): Likewise.
(Get_Exc_Stack_Addr_Soft): Likewise
* s-taspri-vms.ads (Exc_Stack_T): Remove.
(Exc_Stack_Ptr_T): Likewise.
(Private_Data): Remove Exc_Stack_Ptr component.
