mincrypt: support SHA-256 hash algorithm
- adds a library to compute the SHA-256 hash
- updates the RSA verifier to take an argument specifying either SHA-1
or SHA-256
- updates DumpPublicKey to with new "key" version numbers for
specifying SHA-256
- adds new argument to adb auth code to maintain existing behavior
(cherry picked from commit 515e1639ef0ab5e3149fafeffce826cf654d616f)
