INTERPOLATE doesn't work for MergeTree

[yakov-olkhovskiy]

Describe what's wrong
INTERPOLATE doesn't work for tables with ENGINE = MergeTree

Does it reproduce on recent release?
yes

How to reproduce

CREATE TABLE t1 (n Int32) ENGINE = MergeTree ORDER BY n;
INSERT INTO t1 VALUES (1),(3),(3),(6),(6),(6);

SELECT
    n,
    count() AS m
FROM t1
GROUP BY n
ORDER BY n ASC WITH FILL
INTERPOLATE ( m AS m + 1 );

Received exception from server (version 22.5.1):
Code: 47. DB::Exception: Received from localhost:9000. DB::Exception: Missing columns: 'm' while processing query: 'SELECT n, count() FROM t1 GROUP BY n ORDER BY n ASC WITH FILL INTERPOLATE ( m AS m + 1 )', required columns: 'n' 'm', maybe you meant: ['n','n']. (UNKNOWN_IDENTIFIER)

Expected behavior
same as

CREATE TABLE t1 (n Int32) ENGINE = Memory;
INSERT INTO t1 VALUES (1),(3),(3),(6),(6),(6);

SELECT
    n,
    count() AS m
FROM t1
GROUP BY n
ORDER BY n ASC WITH FILL
INTERPOLATE ( m AS m + 1 );
