Fixes#45204
The problem is that ASTSelectQuery::group_by_with_grouping_sets == true
implies ASTSelectQuery::groupBy() but sometimes this wasn't the case. I
added a sanity check a few months ago but had no idea how the AST became
corrupt.
All crashes/exceptions were during AST fuzzing. Looking at
Client/QueryFuzzer.cpp, there is a very small chance to run into the
issue. In detail:
1. In QueryFuzzer::fuzz(), we find that the AST is a ASTSelectQuery and
groupBy() returns true.
2. With small probability, we do
select->group_by_with_grouping_sets = !select->group_by_with_grouping_sets;
where the (default false) group_by_with_grouping_sets flips true.
3. With small probability, we change the expression type in the
following WHERE or PREWHERE if-branches.
This situation is illegal. One possibility is changing the fuzzing code
to not generate it. The fuzzing code is however generic, and doesn't
really care about such details. Therefore, instead add an (theoretically
unnecessary) extra check to ASTSelectQuery::formatImpl() for robustness.

It is not always safe to implicitly rewrite a `tuple` function
call to a literal. Even when the tuple has more then one element
e.g.
`SELECT (tuple(1, 2, 3) AS x).1` is not equivalent to
`SELECT ((1, 2, 3) AS x).1`, the latter is interpreted as
`SELECT tuple((1, 2, 3) AS x).1`.
