Add timeGroup macro without alias

### What happened?

I am using grafana with a Amazon Redshift sql datesource.

The query
`SELECT $__timeGroupAlias(CURRENT_DATE, $__interval)`
does not work as `$__timeGroupAlias` seems to be unknown. (error executing query: ERROR: syntax error at or near \"$\"
Position: 8)

The query
`SELECT $__timeGroup(CURRENT_DATE, $__interval)`
results in
`SELECT floor(extract(epoch from CURRENT_DATE)/300)*300 AS \"time\"` which is not correct as according to the documentation it should not add the "time" alias.

### What did you expect to happen?

- `$__timeGroupAlias` should return what is currently returned by `$__timeGroup`
- `$__timeGroup` should not add an alias

### Did this work before?

I have not tested in with older Grafana versions.

### How do we reproduce it?

Use queries.
