feat: cleanup provider and stack traces logic

[schaable]

This is the final cleanup PR for the network stack in preparation for the alpha (and ideally the beta). It includes:

• Normalized the EDR and HTTP providers to make them as similar as possible.
• Removed the emission of the hardhatNetworkReset event in the request method, as it no longer makes sense in v3.
• Free resources for garbage collection on close (unset the provider for the EDR provider and the dispatcher for the HTTP provider) and throw an error if the request method is called after closing.
• EDR Provider – request method:
  • Removed InvalidInputError logic, as it is already handled by getJsonRpcRequest.
  • Replaced assertions on jsonRpcResponse.result with assertHardhatInvariant.
  • Cleaned up the #handleEdrResponse function.
• Improved functions in stack-trace-solidity-errors.ts by removing TODOs and enhancing overall code flow.
• Made other minor adjustments to improve code clarity and flow.
