Upgrade Encryption to SHA-2 for Android AEP Core SDK

[#1]

StringEncoder.java class in com.adobe.marketing.mobile:sdk-core library supports only SHA-1 and our company requires to have at least SHA-2 for encoding.

Thanks

[#2]

Core SDK supports SHA-256.  It only uses SHA-1 to persist the push token.  All the others are using SHA-256.  You can refer to CacheManger.java.
