FIR: Do not assume indexed assignment is always Unit-coerced

There are three cases where FirUnitExpression might be:
- Empty lambda (not our case)
- Explicit return with no expression (run { return@run })
- Indexed assignment `a[0] = 1`

In the second case, we've got a convention that this should
unconditionally turn the lambda's return type to Unit (see KT-67867)
So, we coerce-to-unit any last expression independently of its type.

But we shouldn't do the same for the third case
