If Proxy "ownKeys" trap is missing, keys are sorted by type in ascending
chronological order.

SetIntegrityLevel ( O, level )
[...]
5. Let keys be ? O.[[OwnPropertyKeys]]().
6. If level is sealed, then
[...]
7. Else,
a. Assert: level is frozen.
b. For each element k of keys, do
i. Let currentDesc be ? O.[[GetOwnProperty]](k).
[[OwnPropertyKeys]] ( )
[...]
6. If trap is undefined, then
a. Return ? target.[[OwnPropertyKeys]]().
OrdinaryOwnPropertyKeys ( O )
[...]
3. For each own property key P of O such that Type(P) is String and P is
not an array index, in ascending chronological order of property creation, do
a. Add P as the last element of keys.
4. For each own property key P of O such that Type(P) is Symbol,
in ascending chronological order of property creation, do
a. Add P as the last element of keys.
5. Return keys.
