Forbid use of java.security.MessageDigest#clone() 

This commit forbids the usage of java.security.MessageDigest#clone() in
favor of getting a thread local instance using
org.elasticsearch.common.hash.MessageDigests. This is to prevent running
into java.lang.CloneNotSupportedExceptions for message digest providers
that do not support clone.

Closes #16543
