rCOMMb62c392ba505: [web] Caclulate encrypted media sha256

Summary

Web counterpart of D7647.
Sometimes encountered weird errors when creating the olm.Utility multiple times so decided to cache the instance and lazy-init Olm.

Due to ENG-3845 I decided to opt out of Olm here and used WebCrypto instead

Test Plan

Added console.log in encryptMedia() and sent encrypted photo. Verified that the hash is calculated

Actually I missed a line here:

let olmUtilityInstance;
function olmUtility(): Promise<Utility> {
  if (!olmUtilityInstance) {
    olmUtilityInstance = (async () => {
      await initOlm();
      olmUtilityInstance = new olm.Utility();
      return olmUtilityInstance;
    })();
  }
  return Promise.resolve(olmUtilityInstance);
}
