Environment

• Qiskit version: 1.2.0.dev0+8f6714d
• Python version: 3.8.19
• Operating system: MacOs

What is happening?

While migrating test/python/transpiler/test_instruction_durations.py to BackendV2 (see #12660 for context), I realized that InstructionDurations.from_backend does not support BackendV2 instances.

How can we reproduce the issue?

from qiskit.providers.fake_provider import GenericBackendV2
from qiskit.transpiler import InstructionDurations

backend = GenericBackendV2(num_qubits=2, calibrate_instructions=True, seed=42)
InstructionDurations.from_backend(backend)

AttributeError: 'GenericBackendV2' object has no attribute 'properties'

What should happen?

Either this method (preferred option) or a potential InstructionDurations.from_backendV2 should support creating an InstructionDurations from a BackendV2, the current preferred way.

Any suggestions?
