fix: notify queries when executing group statements with result

[vitorhugods]

Fixes:

• It's looks like INSERT INTO ...VALUES(...) RETURNING id; not working with coroutines flow #4975
• Inserts not emitted to listeners when using grouping statement #3743
• Inserts not emitted to listeners when RETURNING clause used #4618
• Groupped statements might not notify queries properly #5001

Proposed solution

By modifying the QueryGenerator to make sure all child classes have access to tablesUpdated(), and centralising the query notification into the executeBlock function, make sure the following is added to the generated code of grouped statements.

} .also {
    notifyQueries(queryId) { emit ->
      // emit table names
    }
}

I am not completely sure of this approach and I'd love some feedback before I dedicate more time into it.

To be solved yet

Annoying space before .also {. I'll learn a bit more of Kotlinpoet :)

Questions

• What's the importance of the Query ID? I noticed in some tests it is hardcoded, in some it figures it out from the compiler. I can modify the notifyQueriesBlock() to accept the QueryId and make it match one of the statements.

Remark

I am not sure about the executeBlock. I find its control flow a bit hard to follow and I'd love to simplify a bit and maybe link the QueryGenerator's implementations more closely to implement it depending on what the query looks like, instead of having too many ifs and elses.
