Data.Digest.Sha2: Improve memory management
Rework the SHA-2 implementation to use the low-level sha.h interface
rather than the higher-level evp.h. This allows us to preallocate all
the data structures, eliminating BoringSSL cleanup functions. As a
result, we can implement hashing under `unsafeLocalState` (a.k.a.
`unsafeDupablePerformIO`) instead of `unsafePerformIO`, which should
improve performance in multithreaded programs.
