[Reclaim buffer] Common infrastructure update for reclaiming buffer (#9133)

- Why I did it
This is to update the common sonic-buildimage infra for reclaiming buffer.

- How I did it
Render zero_profiles.j2 to zero_profiles.json for vendors that support reclaiming buffer
The zero profiles will be referenced in PR [Reclaim buffer] Reclaim unused buffers by applying zero buffer profiles #8768 on Mellanox platforms and there will be test cases to verify the behavior there.
Rendering is done here for passing azure pipeline.
Load zero_profiles.json when the dynamic buffer manager starts
Generate inactive port list to reclaim buffer
