"On Demand" option for overlays in Quick Review

[Marsu42]

I like the option to look at focus peaking, Zebras, ... in play mode after pressing the appropriate button when setting "Global Draw" to "Quick Review" or "ON, all modes".

Problem: the overlays are *always* enabled _without_ button press in Quick Review right after taking a shot which draws too much battery power if I just want to have a quick look at the framing and not the exposure.

Request: Add an option "Quick Review GD -> Always on / On demand" for example in Display -> Advanced Settings" to let the user choose if the overlay is applied right away or if a button press is also required in quick review mode after taking the shot just like it is in play mode now.

Global Draw -> LiveView only.

The on-demand option is always active.
