Better dialogue-closing behavior of All Actions

[Half-and-Xat]

Description

When opening the dialogue box All Actions it feels very unhandy to close it again. Currently there are 3 ways:

• Close button (top-right corner)
• Cancel button
• Esc shortcut when All Actions has focus

I wish at least one of two other ways in additional:

• Esc shortcut even when window (but Godot itself) has no focus
• mouse clicking (any button) outside the All Actions window (somewhere inside Godot).

Why is it important?
The current behavior requires clicking with mouse on a specific place of the All Actions window. That slows down the workflow, especially when thinking "wait wrong, have to do the other action first" and already moving with mouse to the other place. A method where the cursor doesn't need to move back to the All Actions window is required keep a good workflow.
