Drop node:process polyfill when v2 is available

[vicb]

The native implementation of process v2 has now all the required APIs so we can drop the polyfill.

Depends on:

• Add further process private exports workerd#5131 which implements

  • _rawDebug

  event properties

  • _events
  • _eventsCount
  • _maxListeners

  undefined

  • _disconnect
  • _handleQueue
  • _pendingMessage
  • _channel
  • _send

  the PR was released in https://github.com/cloudflare/workerd/releases/tag/v1.20250921.0

• add process.assert workerd#5156 which implements process.assert and was released in https://github.com/cloudflare/workerd/releases/tag/v1.20250924.0

Note that the event APIs used to be available on import module from "node:module" while they should not have been, this is an error in unenv.

Thanks @guybedford for the implementation in workerd.
