derive clone for Input (#3569)

Browse source 
# Objective

- As part of exploring input event suppression in bevy_egui here: 53c1773583
- I found that the only way to suppress events properly, is to allow to clone the relevant Input<Whatever>, and update with events manually from within the system. This cloned Input then is discarded, the Events<*> structs are cleared, and bevy_input's normal update of Input proceeds, without the events that have been suppressed.

## Solution

- This enables Input to be cloned, allowing it to be manually updated with events.
