Compute the RuleKey with and without deps simultaneously. Summary: It turns out that a `Hasher` created via `Hashing.sha1()` can have its `hash()` method invoked only once. Therefore, to compute both RuleKeys simultaneously, this diff introduces an AppendingHasher that makes it possible to build up the SHA1 digest for a RuleKey without deps, get its hash, and then update the digest with the deps info, and get its hash again. Test Plan: Created a comprehensive unit test, AppendingHasherTest. The updates to AbstractCachingBuildRuleTest.java reflect the changes to RuleKey.
