fix(clickhouse): escape question marks in DDL (#1140)

The clickhouse client treats `?` in query text as a bind placeholder
and `??` as a literal `?`. DDL and TRUNCATE are sent as query text, so
a column name or text default containing `?` failed with "unbound
query argument", and a `??` default was stored as `?`.

Double every `?` before sending DDL and TRUNCATE, so the server gets
the text unchanged.

Enable the three known-defect tests and allow `?` again in generated
names and defaults.

Fixes PIPE-1284.
