[sdk] v2 Components not supported by LocalClient

Environment

• KFP version: N/A
• KFP SDK version: 1.8.9
• All dependencies version:

kfp                      1.8.9
kfp-pipeline-spec        0.1.13
kfp-server-api           1.7.1

Steps to reproduce

Running this python script

import kfp
import kfp.v2.dsl as dsl

@dsl.component()
def simple():
    print("allo")

@dsl.pipeline(name="test", description="test")
def pipeline():
    simple()

kfp.run_pipeline_func_locally(pipeline, {})

produce:

Expected result

To have the same result as if simple was a v1 component

import kfp
from kfp.components import create_component_from_func
import kfp.dsl as dsl

@create_component_from_func
def simple():
    print("allo")

@dsl.pipeline(name="test", description="test")
def pipeline():
    simple()

@chensun @gpoulin-hopper Actually I have implemented the local client for v2 which is only used internally for now. If needed I will be happy to pull a PR.

@lynnmatrix yes please!
