Move concept for node-matter -> matter.js

MOVE_CONCEPT.md

How to move code/classes/files?

• Directory "codec" (with exports)
  • all "Schema" ones (PairingCode and QRCode) -> matter.js/schema
  • Rest (codecs) -> mtter.js/codec
• Directory "crypro" (with exports)
  • make crypto a signleton
  • Move Crypto (basis) and Spake2 --> matter.js/crypto --> This adds BN and eliptic as deps to matter.js
  • Leave a "CryptoNode" in node-matter directory crypto
• Directory "error" -> matter.js/common/ (with exports)
• Directory "log" -> matter.js/util/log (with exports)
• Directory "math" -> matter.js/math (no exports)
• Directory "matter/certificate" -> matter.js "certificate" (with exports)
• Directory "matter/cluster" -> matter.js/cluster (with exports)
• Direcory "matter/common" -> matter.js/common (with exports)
• Directory "matter/fabric" -> matter.js/fabric (with exports)
• Directory "matter/interaction" -> matter.js/protocol/interaction (with exports)
• Directory "matter/mdns" -> matter.js/mdns ... or we start a matter.js/communication/mdns (and also move net in there) (with exports)
• Directory "Matter/session"
  • Basic session types --> matter.js/session
  • session/secure/Pase* -> matter.js/session/pase
  • session/secure/Case* -> matter.js/session/case
  • session/secure/SecureChannel* -> matter.js/protocol/securechannel
• Directory "net"
  • basically -> matter.js/net
  • the nodejs specific parts that staay there with Filename *Node (so remove extra directory "node")
• Directory "storage"
  • all general Files and types -> matter.js/util/storage
  • StorageBackendDisk stays
• Directory "time" -> matter.js/util/time
• Directory "util" -> matter.js/util
• Files matter/MatterDevice and matter/MatterController -> root of matter.js (will be replaced pot anyway when API is updated)

After this in matter-node.js we should have structure like:

• crypto
  • CryptoNode.ts
• net
  • NetworkNode.ts
  • UdpChannelNode.ts
• persistence
  • StorageNode.ts
• time
  • TimeNode.ts
• ControllerNode.ts
• DeviceNode.ts

How to export all the needed things?

• Flat export as of currently - has big downsides becausethen the naming of All exported entities in whole matter.js need to be unique (that already breaks now with StatusCode and EffectVariant)
• We could use modules to export "by topic" and only have a very few global exports
  • This means that users do "import { AccessControlCluster } from "@project-chip/matter.js/cluster" - so we define modules "by topic" toexport ... the modules could match to our above directory structure

before refactoring I recommend getting all the expected exports promoted to the @project-chip/matter-node.js index.ts so that consumers of the library don't have to rework their imports. I'll do the work and get a PR in place.

@vves in fact matter-node will only export the "nodejs specific" classes. This is a handful of exports. All rest will move to matter.js together with the code. Ok, looking forward for your PR, but 9x% of the exports come from matter.js in the future!
