fix: fix enforcing up to date ControlPlane's ClusterRole and ClusterRoleBinding

[pmalek]

What this PR does / why we need it:

There was an error in the patching logic were the controller would try to patch using a generated resource and this getting:

2024-03-14T17:43:26Z	ERROR	Reconciler error	{"controller": "controlplane", "controllerGroup": "gateway-operator.konghq.com", "controllerKind": "ControlPlane", "ControlPlane": {"name":"aigateway-test-8cnvx","namespace":"4e1a7586-c08c-4d11-b421-763dad2f6767"}, "namespace": "4e1a7586-c08c-4d11-b421-763dad2f6767", "name": "aigateway-test-8cnvx", "reconcileID": "17f23e6e-b72b-4036-8bf9-4cb45cd00eec", "error": "failed patching ControlPlane's ClusterRoleBinding controlplane-aigateway-test-8cnvx-rgwnj: the name of the object (controlplane-aigateway-test-8cnvx-rgwnj based on URL) was undeterminable: name must be provided"}

failed patching ControlPlane's ClusterRoleBinding controlplane-aigateway-test-8cnvx-rgwnj: the name of the object (controlplane-aigateway-test-8cnvx-rgwnj based on URL) was undeterminable: name must be provided

This PR fixes that both for ClusterRole and ClusterRoleBinding.

This should fix the flakiness in several of the integration tests that deploy and update ControlPlanes (directly or indirectly).

Exemplar failure on CI: https://github.com/Kong/gateway-operator-archive/actions/runs/8285193525/job/22672382974?pr=1592#step:4:3602

To reproduce that locally it's enough to edit either of those resources on the cluster. Either change one of the ClusterRole's policy rules or ClusterRoleBinding's subjects.

The test that's in place

gateway-operator/controllers/controlplane/controlplane_controller_reconciler_utils_test.go

Lines 186 to 187 in 8f01deb

	func TestEnsureClusterRoleBinding(t *testing.T) {

did not catch that because fake client doesn't detect this type of errors.
