Move "Build Android App Bundle" and "Open Package Location" option from Build settings to Build menu

On Android AAB builds are only used for publishing to the Play Store and is not done all that often as part of development process, having the option to build AAB and opening the package location under Build settings is not that good usability, if you want to build an AAB you'd have to first enable the two options, build, then disable them again. This feature should be under the Build menu where it can be accessed once when needed to create a final AAB package and after the build the location of the artifact is opened by default.

Along the way, an option to build an APK and show the output folder can be added at the same time.
