core/crypto/sha2: Refactor update/final
...
This is largely modeled off the SM3 versions of these routines, since
the relevant parts of the code are the same between SHA-256 and SM3,
and the alterations required to support SHA-512 are relatively simple.
The prior versions of update and the transform would leak memory, and
doing things this way also reduces the context buffer sizes by 1 block.

core/crypto: Add more assertions to the low level API
...
Assertions here are "fine" and it matches what the code that has the
checks in init/update/final already does.

core/crypto: Change hash asserts to panics
...
Assertions can be disabled, but at the point where cryptographic
anything is involved, a single branch has an infinitesimally small
performance impact.
The correct thing to do is to punch the caller in the face if they do
something that is blatantly incorrect, especially in a security critical
setting.
