[karmadactl get] judge with label on the resources determine whether resource is adopted by Karmada

[XiShanYongYe-Chang]

What type of PR is this?

/kind cleanup

What this PR does / why we need it:

We have added labels to the resources in the member cluster to indicate whether the current resource is propagated by Karmada:

karmada/pkg/util/constants.go

Lines 26 to 30 in 1953a0e

	// ManagedByKarmadaLabel is a reserved karmada label to indicate whether resources are managed by karmada controllers.
	ManagedByKarmadaLabel = "karmada.io/managed"
	// ManagedByKarmadaLabelValue indicates that resources are managed by karmada controllers.
	ManagedByKarmadaLabelValue = "true"

Therefore, we can directly process this label in the karmadactl get command, without needing to retrieve RB/CRB resources.

Which issue(s) this PR fixes:
Fixes #

Special notes for your reviewer:

One reason for this change is that we cannot assume that users using karmadactl by default have the authority to get rb/crb resources.

Does this PR introduce a user-facing change?:

NONE
