AAB(Android App Bundle) Support

[rupeshkumar22]

Fixes #594

As AAB is the only way to distribute apps on Google Play Console. This PR adds a feature to generate signed AAB and Unsigned AAB. For Testing purposes, a universal APK was created with the help of bundletool.jar(included in SDK) from generated AAB file and installed on the emulator. No issue has been faced by doing so.

Generates AAB files as- Documents/Processing/sketch_210923a/buildBundle/sketch_210923a_release_signed.aab Documents/Processing/sketch_210923a/buildBundle/sketch_210923a_release_unsigned.aab

Regenerates Bundles similar to export-package utility as - Documents/Processing/sketch_210923a/buildBundle.210924.0527/sketch_210923a_release_signed.aab Documents/Processing/sketch_210923a/buildBundle.210924.0527/sketch_210923a_release_unsigned.aab

Method of initiating the task File -> Export Signed Bundle

Keyboard Short Cut Ctrl + B

Thanks for this amazing contribution @rupesh-kumar-lpu :partying_face:

Do you have any kind of high level design doc for this feature or a rough idea how you have done this with the existing processing-android codebase ?

Thanks.

For implementing this I tried to reuse the existing functions. The implementation is pretty much similar to the "Export Signed Package". The origin of implementation starts from the 'JMenuItem' click handler in the AndroidEditor.java file. All the functions used for "Export Signed Package" were reused with slight modification(providing certain function parameters) to distinguish the use of AAB or APK tasks. For example, KeystoreManager's constructor was modified to pass the boolean type (forBundle) to distinguish about the exporting task.

Thanks for reviewing the changes @ranaaditya
