Cancel previous runs of the same PR automatically (#29961)

Follow #25716. Also cancel previous runs for `pull_request_sync`.

It's not a bug since it original PR said "if the event is push".

The main change is
https://github.com/go-gitea/gitea/pull/29961/files#diff-08adda3f8ae0360937f46abb1f4418603bd3518522baa356be11c6c7ac4abcc3.

And also rename `CancelRunningJobs` to `CancelPreviousJobs` to make it
more clear.
