What does this PR do?

Part of #16539

Since #16539 removes the concept of optimizer index, and toggle/untoggle methods will be useful for working with multiple optimizers in manual optimization, this PR makes it more convenient to use these methods by taking the optimizer object directly instead of the index.

Does your PR introduce any breaking changes? If yes, please list them.

Argument optimizer_idx gets removed from both methods. Part of the Trainer 2.0 loop simplification initiative.
