Proposal: Make AppInspect open on click

Summary:
This addresses my biggest gripe with Flipper right now (maybe after it occasionally crashing my entire Mac, but that's beyond our control, sadly). When you try to switch your current device and hover over the picker, move your mouse quickly to where you expect the menu to open, it will immediate close. You have to wait for about 200ms before moving your cursor down into the expanded dropdown menu. "Well, it's only 200ms, Passy, chill." That's fair, but I still think that hovering to open a dropdown is unnatural behaviour. Looking around here in Phabricator, none of the dropdowns behave like this. And they definitely don't just disappear under my cursor if I'm Moving (too) Fast.

Changelog: The app selector no longer reacts on hover events now requites a click
