Directly constrained lists containing indirectly constrained aggregate shapes generate uncompilable code

[drganjoo]

Issue: Code generation fails for directly constrained list with indirectly constrained aggregate shapes

When generating code for a model where a list contains a non-constrained map with a constrained key, an error occurs during server-side code generation.

operation SampleOp {
    input := {
        items: ItemList
    }
    errors: [ValidationException]
}
@length(min: 1, max: 100)
list ItemList {
    member: Item
}
map Item {
    key: ItemName,
    value: ItemDescription
}
@length(min: 0, max: 65535)
string ItemName
string ItemDescription

This also happens if the constrained list contains another indirectly constrained list as a member.

operation SampleOp {
    input := {
        items: ItemList
    }
    errors: [ValidationException]
}
@length(min: 1, max: 100)
list ItemList {
    member: Item
}
list Item {
    member: ItemName,
}
@length(min: 0, max: 65535)
string ItemName
string ItemDescription
