Nav: Made Enter key submit the same type of Activation event as Space key. (#5606) 

Instead of adding NavActivateInputId support in ButtonBehavior() started untangling the mess.

- Nav: Made Enter key submit the same type of Activation event as Space key,
allowing to press buttons with Enter. (#5606)
(Enter emulates a "prefer text input" activation vs.
Space emulates a "prefer tweak" activation which is to closer to gamepad controls).
- Drag and Drop: Fixed handling of overlapping targets when smaller one is submitted
before and can accept the same data type. (#6183).
- Drag and Drop: Clear drag and drop state as soon as delivery is accepted in order to

USING GAMEPAD/KEYBOARD NAVIGATION CONTROLS
USING KEYBOARD/GAMEPAD NAVIGATION CONTROLS
------------------------------------------
- The gamepad/keyboard navigation is fairly functional and keeps being improved.
- The keyboard/gamepad navigation is fairly functional and keeps being improved.
- Gamepad support is particularly useful to use Dear ImGui on a console system (e.g. PlayStation, Switch, Xbox) without a mouse!
- The initial focus was to support game controllers, but keyboard is becoming increasingly and decently usable.
- Keyboard:
- Application: Set io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard to enable.
- Arrow keys to move. Space or Enter to activate (on a slider/drag: Space will tweak with arrow, Enter will input text).
- When keyboard navigation is active (io.NavActive + ImGuiConfigFlags_NavEnableKeyboard),
the io.WantCaptureKeyboard flag will be set. For more advanced uses, you may want to read from:
- io.NavActive: true when a window is focused and it doesn't have the ImGuiWindowFlags_NoNavInputs flag set.
