Include resource parameter in token exchange requests for OAuth2 flow to comply with RFC 8707.
The resource indicator was previously only included in the authorization request but missing
from both the authorization code and refresh token exchange requests.

This fix ensures that when a resource is specified in the metadata, it is consistently
included in all OAuth2 requests:
- Authorization request (already implemented)
- Authorization code for token exchange (now fixed)
- Refresh token exchange (now fixed)

Fixes #261364

* fix: confirm response based on promise

When using the new `workbench.action.chat.open.blockOnResponse`
feature, if the VSC instance was in auto-approve mode, it was observed
that the command was resolving before the tool finished invocation.

This resulted in a race betwee sync and async code:

```
		if (!this._confirmationMessages) {
			// No confirmation needed
			this._isConfirmed = { type: ToolConfirmKind.ConfirmationNotNeeded };
			this._confirmDeferred.complete(this._isConfirmed);
		}
```

and then the check for confirmation in `isConfirmed`.

* remove _isConfirmed in favor of always the promise

* better reasoning rendering

* settings cleanup

* another settings update, changing defaults

* some more cleanup, no more helper func
