Cast inside aggregate (e.g. int → long) cannot be translated

[AlekseyMartynov]

Any chance this can be fixed in 2.x?

dbSet
    .GroupBy(i => 1)
    .Select(g => new {
        c = g.Count(),
        s = g.Sum(i => (long)i.Int32Prop)
    })
    .ToArray();

Error generated for warning 'Microsoft.EntityFrameworkCore.Query.QueryClientEvaluationWarning:
The LINQ expression 'GroupBy(1, [i])' could not be translated and will be evaluated locally.'

Triage: this is something we will look at in 3.0. Unfortunately, there is no chance of fixing it in a patch release.

@smitpatel removing propose-punt as discussed in triage. IIRC, we said this issue was likely to be fixed.
