Excluded keys should not be performed with GetOwnPropertyDescriptor on
source object in CopyDataProperties.
The key values fetch in CopyDataProperties might be arbitrary kind. It
may be smi, string, and symbol. Yet the proxy keys collected by
KeyAccumulator are not expected types for numeric keys. Those keys
should be converted to expected types.
Also updates a typo in comments of
BytecodeGenerator::BuildDestructuringObjectAssignment. The elements in
rest_runtime_callargs should be [value, ...excluded_properties].
