[TIMOB-25877] Android: "Ti.Platform.ostype" wrongly returns "32bit" on a 64-bit OS

*Summary:* The Ti.Platform.ostype property is currently hardcoded to return "32bit" on Android. [APSAnalyticcsHelper.java#L235](https://github.com/appcelerator/aps_sdk/blob/195633dd10a37d96ecf52be35c0c712dff5ef331/android/analytics/APSAnalytics/src/main/java/com/appcelerator/aps/APSAnalyticsHelper.java#L235) Now that Titanium supports building Android apps for ARM64, it should return "64bit" when running on a 64-bit Android device like how it works for iOS here... [APSUtility.m#L15](https://github.com/appcelerator/aps_sdk/blob/195633dd10a37d96ecf52be35c0c712dff5ef331/ios/support/analytics/APSAnalytics/APSUtility.m#L15) *Steps to Reproduce:*

Build an run the below code on a 64-bit Android device, such as a Pixel XL phone.

Observe the log for an "ostype:" entry.

Ti.API.info("@@@ ostype: " + Ti.Platform.ostype);

*Note:* We had to do something similar for iOS as can be seen here: [TIMOB-18193] *Recommended Solution:* Check if array returned by android.os.Build.SUPPORTED_64_BIT_ABIS contains at least 1 element. https://developer.android.com/reference/android/os/Build.html#SUPPORTED_64_BIT_ABIS Note that Google added 64-bit support as of Android 5.0 (aka: API Level 21). So, you can't use Google's Process.is64Bit() method since it is only supported on Android 6.0 and higher. https://developer.android.com/reference/android/os/Process.html#is64Bit()
