Issue:
[ADAP-734] [Bug] When dbt is stopped with ctrl+c, queries are logged as cancelled, but continue to run on the database.
### Is this a new bug in dbt-snowflake?

- [X] I believe this is a new bug in dbt-snowflake
- [X] I have searched the existing issues, and I could not find an existing issue for this bug

### Current Behavior

When I stop dbt during query execution with `ctrl+c`, the system function `system$abort_session(session_id)` is executed. This ends the session, but seems to orphan any queries executing within the session.  I can see the queries continue to run in the snowflake query history pane.

### Expected Behavior

All queries being executed within a session should be aborted with ctrl+c. 

### Steps To Reproduce

1. Write a new model `models/example/slow_model.sql` that selects from a large table or is slow to execute.
2. Execute `dbt run -m slow_model`  
3. While this is running, hit ctrl+c at the dbt command line 
4. Wait for dbt to cancel query, exit, raise `KeyboardInterrupt` and return back to shell.

Then, observe in snowflake query history pane two things: `system$abort_session(session_id)` succeeded, and the slow model is still running. 

To kill this slow model, copy session id, open Snowflake SQL worksheet and execute 
```sql
select system$cancel_all_queries(0123456789);
```
replacing `0123456789` with your query's session ID. 

Output: `1 cancelled.`

### Environment

```markdown
- OS: MacOS Ventura 13.4 (M1 macbook pro)
- Python: 3.9.6
- dbt-core: 1.5.1
- dbt-snowflake: 1.5.1
```


### Additional Context

I think the issue could be resolved by replacing `system$abort_session` with `system$cancel_all_queries` on this line https://github.com/dbt-labs/dbt-snowflake/blob/main/dbt/adapters/snowflake/connections.py#L387 but I have not tested this.

  before this PR is merged?
-->

The queries arent cancelled after typing ctrl + c in console, this might have several performance issues

```
to
```console
system$cancel_all_queries(session_id)
```
