Memory usage fixes for Haddockwip/haddock-mem-fixes

- Do not include `mi_globals` in the `NoBackend` backend. It was only included
  for Haddock, but Haddock does not actually need it. This causes a 200MB
  reduction in max residency when generating haddocks on the Agda codebase
  (roughly 1GB to 800MB).
- Strictly evaluate some SrcSpans in mkDoc{Next,Prev} to avoid thunks
- Strictly evaluate names in rnHsDoc to avoid retaining entire GlobalRdrEnv
- Update Haddock submodule
