tcon: Encode information on container members in "type" canaries

Add "container canaries" to tcon.  This allows information about a specific
member of a container structure to be encoded with TCON or TCON_WRAP.  Once
that's done, tcon_container_of() and tcon_member_of() can be used to
translate between member and container pointers based on the canary
information, without having to repeat the type and member details.
