binding feedback on interaction

[mwestphal]

Is your feature request related to a problem? Please describe.
When interacting with F3D and pressing binds, there is not much feedback except on the cheatsheet or obviously visually.

Let's add a visual feedback that disapear after a while.

How

• Add an ImGui window dedicated to display interactive binds, probably bottom right
• When pressing a bind, display a reference to that interaction there for a few seconds
• When pressing multiple binds, they should stack vertically
• Backdrop should be present, extending but disapear too if nothing is shown

Are there any events other than key presses that should trigger one of these notifications? and if so does it affect the design for the implementation?

I'm thinking of when a file is reloaded with --watch for example

Hum, I did not think of that but I suppose, yes.
