Retrieve a custom value identified by key from the render param's implementation.
The value could have been set via SetArbitraryValue() or provided internally by the render param. Return an empty VtValue if no value is associated with the key. This can either be used to retrieve arbitrary values by the render delegate or by Hydra client code. Since this method can be called by client code, it must be thread-safe.

Check whether a valid custom value exists for the specified key in the render param's implementation.
Returns true if the value exists, false otherwise. Since this method can be called by client code, it must be thread-safe.
Set a custom value in the render param's implementation.
The key identifies the value, while value holds the data to set. Return true if the value was successfully set, false if the operation is not supported for the specified key or value. Since this method can be called by client code, it must be thread-safe.
