Suggestion: Add deploy menu

Applications are more and more deployed via app stores. At the moment most deployment steps have to be done manually. Integration of a deployment feature would be a real time saver. It would also reduce the entry barrier for new Qt users.

In the following text a new menu "Deploy" which opens a new dialog for each platform with options for Android, iOS, macOS, and Windows is suggested. Similar menus are known from xCode ("Archive") and Android Studio ("Create signed APK").

All platforms

• Option for clean before build.
• Eventually option for DEFINES only activated during the deploy step.

Android

• Select architectures (armv7, 8, x86, etc.) for multi-abi build.
• Open package location after build.
• Selection of signing keys.

iOS

• Open the xCode project in xCode or open the folder containing the xCode project.

Windows

• Select target directory.
• Run windeploy.
• Open directory after windeploy.
• Eventually allow execution of batch file after windeploy (e.g. for creating installers).

macOS

• Selection of signing key (app store / outside of app store distribution).
• Select entitlements file.
• Run macdeploy (with signing).
• Create pkg after macdeploy.
• Upload option to macOS notarization service.
• Button for finishing notarization after email from notarization service.
• Open directory with pkg after macdeploy.
