[InputSystem] ButtonControl API calls produce duplicate / missing calls when working with Trigger Button
How to reproduce:
1. Open the user attached "InputSystem_TriggerIssue.zip" project
2. Open the "SampleScene" Scene found in the Assets folder
3. Connect an XboxOne or PS4 or PS5 controller
4. Enter Play Mode
5. Open the Console
6. Press the Right Trigger on the controller and release multiple times
Expected result: Consistent counts of "Pressed" and "Released"
Actual result: Inconsistent counts
Reproducible with: 1.1.1 (2019.4.36f1), 1.2.0 (2019.4.36f1, 2022.2.0a3), 1.3.0 (2019.4.36f1, 2020.3.27f1, 2021.2.10f1, 2022.1.0b6, 2022.2.0a3)

Resolution Note:
In the bug the user was checking if(bc.wasPressedThisFrame) {...} else if(bc.wasReleasedThisFrame) {...} from button action callback bound to trigger.
If button was pressed and released in the same frame, it will not be possible to see second part executed.
Actions generally go via different mechanism of action phases, started->performed->canceled. So if we try printing them out like this:
if(context.started)
Debug.Log("Started");
else if(context.performed)
Debug.Log("Performed");
else if(context.canceled)
Debug.Log("Released");
Then in all cases it prints either Started->Performed->Released or Started->Released.
