Problem

Sha256 is implemented with the sha256compression opcode in PR AztecProtocol/aztec-packages#4511
When this PR is merged, we no longer need the sha256 opcode

Happy Case

Just remove the sha256 opcode. The implementation with sha256 compression is more performant and allows us to have a variable size sha256

Pending for AVM's update to support SHA256 compression opcode, so we can safely deprecate this.

This PR resolves Noir issue 4330:
noir-lang/noir#4330

stdlib by the implementation using the sha256 compression opcode (also
in the stdlib).

Doesn't look like it need any, but do create an Issue if any updates to the SHA256 section in docs is necessary, thanks!
