feat(android): exclude x86/x86_64 in production builds by default

[jquick-axway]

JIRA:
https://jira.appcelerator.org/browse/TIMOB-27752

Summary:

• When doing a "production" build, Titanium should exclude x86 and x86_64 architectures from app by default.
• You can override this behavior via <abi/> setting in "tiapp.xml".
• This maintains the same behavior we had since Titanium 7.0.0.

Test:

1. Build an app for Android depoyment type "development" or "test".
2. Go to folder: ./build/android/app/build/outputs/apk/debug
3. Unzip the APK file.
4. Verify that you see the following unzipped sub-folders:

• ./lib/armeabi-v7a
• ./lib/arm64-v8a
• ./lib/x86
• ./lib/x86_64

5. Build an Android "production" app.
6. Unzip the APK.
7. Verify that you see the following unzipped sub-folders:

• ./lib/armeabi-v7a
• ./lib/arm64-v8a

8. Add the below <abi/> entry to the "tiapp.xml" file.

<ti:app xmlns:ti="http://ti.appcelerator.org">
	<android>
		<abi>armeabi-v7a,arm64-v8a,x86,x86_64</abi>
	</android>
</ti:app>

9. Build an Android "production" app.
10. Unzip the APK.
11. Verify that you see the following unzipped sub-folders:

• ./lib/armeabi-v7a
• ./lib/arm64-v8a
• ./lib/x86
• ./lib/x86_64

FR Passed.

1. When performing a test/development build of a mobile project the apk generated includes all four architectures (arm64-v8a, armeabi-v7a, x86, x86_64)
2. When performing a production build of a mobile project the apk generated has arm64-v8a, armeabi-v7a architectures.
3. When performing a production build of a mobile project and including information for all 4 abi's in Tiapp.xml the apk generated includes all four architectures.
4. When the mobile project uses any module that uses SDK prior to 9.0 then the test/development/production build for the mobile project excludes the x86_64 architecture. Also a warning message is logged in the build logs.
