Closes https://github.com/twentyhq/core-team-issues/issues/1563.
We now have two inter-group orderBy criteria: one on the aggregate
values, the other on the dimension values.
Ex: I am grouping companies by city and querying the average number of
employees for each group. I can either order the groups by the city
name, or by the average number of employees, or by one then the other.
I could actually also order groups by an aggregated value that I did not
ask for (ex: average ARR), but I cannot order groups by a field value I
did not group records by (ex: country).

An example of query variables:
```
{
"groupBy": [
{
"createdAt": {
"granularity": "QUARTER_OF_THE_YEAR"
}
},
{"city": true}
],
"orderBy": [
{
"aggregate": {
"avgEmployees": "DescNullsLast"
}
},
{
"aggregate": {
"percentyEmptyEmployees": "DescNullsLast"
}
},
{
"city": "AscNullsLast"
},
{
"createdAt": {
"orderBy": "AscNullsLast",
"granularity": "QUARTER_OF_THE_YEAR",
}
}
]
}
```
The aggregate orderBy criteria had already been implemented, but I
updated the implementation to add an "aggregate" key to prefix them, in
order to avoid confusion between the two + for the schema generation not
to break (otherwise we would have an issue when generating
OrderByWithGroupByInput if a user has created a field that has the same
name as an aggregate field, such as avgEmployees).
