This enables to create a C archive with Ebiten without an actual driver implementation. This enables Ebiten work on a platform Go doesn't support. See also Hitsumabushi project: github.com/hajimehoshi/hitsumabushi. The backend C API is not stable and might change later. Then, the build tag 'ebitencbackend' is not documented on purpose. Closes #1900
