[cherry-pick] use the required instruction to determine if the environment fits the sample code's required.  (#32766) (#33451)

1 put a instruction # required: gpu(for example) in the sample code
2 this piece of code will only run in the GPU-equipped CI pipelines, and be omitted in other pipelines.
3 the CI pipelines can specify its capacity by shell environment variable SAMPLE_CODE_TEST_CAPACITY
