DIRECTOR: Implement "return to launcher" feature for Director games

[Thunderforge]

The "Always return to the launcher when leaving a game" option does not get respected for Director engine games.

Reproduction steps

1. Go to "Options…" → "Misc" and check "Always return to the launcher when leaving a game"
2. Open any Director game (tested on Spaceship Warlock Demo 1.1.1 and several others)
3. Click the close window button

ScummVM will quit instead of returning to the launcher.

Versions

• ScummVM x64 2021-08-23 (g8812574dc8)
• macOS 11.5.2

The issue is not specifically with the option to always return to the launcher when leaving a game. You cannot return to the launcher from the GMM either as the director engine currently does not support returning to the launcher.

However the option label could maybe be improved since "Always" is a bit misleading (although always refers to the different way you can quit a game rather than to the different games).

I guess either solution would be acceptable for the purposes of resolving this issue:

1. Add support to the Director engine for returning to the Launcher
2. Somehow changing the setting to convey to users that enabling it allows them to return to the launchers on some engines such as SCUMM, but not other engines such as Director (the user shouldn't be surprised about which ones it happens for).

Issue addressed in this PR ​4544.
Dropped the "always" and indicated in the tooltip that not all games support the feature (besides Director, I'm sure that Blazing Dragons does not support it as well, and probably other less-common engines).
