✨ Add createEDCH support

[Apollon77]

What feature or enhancement are you suggesting?

We currently trying to get https:/project-chip/matter.js running in react-native to allow developers to build Matter compatible devices or controllers as mobile applications.
Matter.js is a "pure JavaScript "implementation of the Matter iot standard, but it requores some platform specific functionalities like Crypto. For node.js we alraeyd have a package that uses the nodejs "crypto" module - https:/project-chip/matter.js/blob/main/packages/matter-node.js/src/crypto/CryptoNode.ts

We now try to build the same for react native and use your implementation as "nodejs like drop in replacement" (see https:/project-chip/matter.js/blob/main/packages/matter.js-react-native/src/crypto/CryptoReactNative.ts)

So we also need createEDCH ...

What Platforms whould this feature/enhancement affect?

iOS, Android

Alternatives/Workarounds

We are currently iterating in a development environment and use https://www.npmjs.com/package/create-ecdh with a patched brorand sub library (because we need to tweak the wy it initializes) and that seems to work, but would be cool if it would be integrated :-)
