[TIMOB-26376] Android: Remove "commons-codec.jar" and replace with Java "MessageDigest"

*Summary:* The Titanium SDK currently uses the Apache "commons-codec.jar" to generate MD5 hashes for its JavaScripts APIs such as Ti.Utils.md5HexDigest() and internally via the Java DigestUtils class. We should remove this JAR file to reduce APK bloat and replace its usage with the built-in Java "MessageDigest" class provided by Android here... https://developer.android.com/reference/java/security/MessageDigest To simplify the transition, we can create our own Titanium TiDigestUtils Java class to ease the transition internally. *Note:* This was changed was suggested when Apache hashing broke when an app targets Android P. Please see the discussion in the PR below... https://github.com/appcelerator/titanium_mobile/pull/10253
