ZK-559: Add wasm implementation for CryptoClient

[kroist]

This pull request includes a new package shielder-sdk-crypto-wasm which is basically a standalone /crypto module from shielder-sdk, implementing CryptoClient interface for WASM web target.

Main Changes

Most of the code is similar to /crypto module, however:

• Introduced modular structure, where each module has single responsibilty on wrapping its functionality from WASM.
• Added src/utils/wasmModuleLoader.ts base classes to reduce a lot of code duplications
• Removed duplicate code/wrappers from /src/wasmClientWorker.ts and /src/wasmClient.ts

Vite Patch

During the extension build with WXT framework (which uses vite under the hood) it was found out that shielder-sdk didn't properly bundle:

• code inside WebWorkers wasn't included
• WASM code wasn't included

To adress this issue I added ./vite, ./wasm_singlethreaded and ./wasm_multithreaded entrypoints in package, which would allow to use the vite distribution, which is basically the original distribution with vite-suggested WebWorkers declaration (as currently used in extension). The usage is documented in README.md

Well, I have to say in Polish "kawał dobrej roboty", somehow similar phrases in English don't sound the same. Just a few small comments to clarify.

If I understand correctly, this improves the worker interface a lot, we're not forced to do everything through worker methods anymore, awesome!

Really happy to get rid of all these blocks

  constructor(caller: Caller) {
    this.caller = caller;
    if (caller == "web_singlethreaded") {
      this.wasmModule = singleThreadedWasm;
    } else if (caller == "web_multithreaded") {
      this.wasmModule = multiThreadedWasm;
    } else {
      throw new Error("Invalid caller");
    }
  }
