Consistently truncate non-key suffix columns.
INCLUDE indexes failed to have their non-key attributes physically
truncated away in certain rare cases. This led to physically larger
pivot tuples that contained useless non-key attribute values. The
impact on users should be negligible, but this is still clearly a
regression (Postgres 11 supports INCLUDE indexes, and yet was not
affected).
The bug appeared in commit dd299df8, which introduced "true" suffix
truncation of key attributes.

Backpatch: 12-, where "true" suffix truncation was introduced.
