Implement actions artifacts (#22738)

Implement action artifacts server api. This change is used for supporting https://github.com/actions/upload-artifact and https://github.com/actions/download-artifact in gitea actions. It can run sample workflow from doc https://docs.github.com/en/actions/using-workflows/storing-workflow-data-as-artifacts. The api design is inspired by https://github.com/nektos/act/blob/master/pkg/artifacts/server.go and includes some changes from gitea internal structs and methods. Actions artifacts contains two parts: - Gitea server api and storage (this pr implement basic design without some complex cases supports) - Runner communicate with gitea server api (in comming) Old pr https://github.com/go-gitea/gitea/pull/22345 is outdated after actions merged. I create new pr from main branch. ![897f7694-3e0f-4f7c-bb4b-9936624ead45](https://user-images.githubusercontent.com/2142787/219382371-eb3cf810-e4e0-456b-a8ff-aecc2b1a1032.jpeg) Add artifacts list in actions workflow page.
