[roll third_party/pigweed] pw_crypto: Refactor Sha256

1. Extracts state tracking from backends to the facade, with tests
   against a mocked backend.

2. Makes Sha256::Update() chainable. e.g.
   ```
   if (!Sha256().Update(message).Update(more_message).Final().ok()) {
       // Handle errors.
   }
   ```
   All usage and documentation are updated accordingly.

3. Inlines Sha256::Sha256()/Update()/Final() in sha256.h, removes
   sha256.cc.

4. Other trivial clean ups.

Test:
  - `pw presubmit`
  - `pw presubmit --step gn_crypto_(mbedtls|boringssl|micro_ecc)_build`
