Run CircleCI jobs in seperate workflows to enable rerunning individually

[akihironitta]

What does this PR do?

Enables individually rerunning the two circleci jobs, build-Docs and TPU-tests by dividing the workflow into two for each job.

Just trying... not 100% sure if it works. It seems working correctly :)

@Borda I think I have to ask someone with a higher privilege to change the setting in this repo. Could you update it after (or before?) this PR lands if you can?

yep, we know, need Admin to update the required checks and the rename drops the original and creates two new ones instead... :)

[carmocca]

Let's change that after the release so current PRs don't need to re-run their CI

@akihironitta ping me if I forget!

Hi @Borda @carmocca, this is nothing urgent, but could you ping @lexierule to update the setting for required jobs so that we can merge this PR?

[Borda]

to update the setting for required jobs so that we can merge this PR?

I was checking with her last week, and for some reason, the next CicleCI job is not visible... would need to check again

@Borda Any idea why the old one is still required as seen in #12614?
