WASM: Add SHA* hash functions (#40486)

This ports the managed SHA* hash functions from https://github.com/microsoft/referencesource so we can use them on Browser/WASM where we don't have OpenSSL.

Enables the System.Security.Cryptography.Algorithms tests for these classes: `Tests run: 271, Errors: 0, Failures: 0, Skipped: 1. Time: 11.857137s`

Resolves #40076
