[BUILD] Close stale PRs

## What changes were proposed in this pull request?

This PR proposes to close stale PRs.

What I mean by "stale" here includes that there are some review comments by reviewers but the author looks inactive without any answer to them more than a month.

I left some comments roughly a week ago to ping and the author looks still inactive in these PR below

These below includes some PR suggested to be closed and a PR against another branch which seems obviously inappropriate.

Given the comments in the last three PRs below, they are probably worth being taken over by anyone who is interested in it.
