[Docs] Clean up stale references from recent refactors (#18908)
This is a follow-up pr of #18906
- **Removed "Unity" branding**: Replace "Apache TVM Unity" with "Apache
TVM" across all docs (Unity branch has been merged into
main)
- **Fixed stale Python APIs**: `tvm.instrument` → `tvm.ir.instrument`,
`tvm.transform` → `tvm.ir.transform`, `tvm.module.Module` →
`tvm.runtime.Module`, `tvm.convert` → `tvm.runtime.convert`,
`tvm.runtime.load` → `tvm.runtime.load_module`
- **Fixed S-TIR migration**: `tvm.tir.transform.DefaultGPUSchedule` →
`tvm.s_tir.transform.DefaultGPUSchedule`; added missing
`s_tir/transform` API doc page
- **Removed references to deleted features**: AutoTVM/AutoScheduler
(removed), FewShotTuning (phased out in #18864), i386 CI
(removed in #18737), VTA (removed), TensorFlow frontend (not in Relax),
MXNet/Gluon (archived)
- **Fixed stale C++ references**: `NodeRef` → `ObjectRef`, `make_node` →
`ffi::make_object`, removed unused `using
tvm::runtime::Registry`, `src/relax/transforms/` →
`src/relax/transform/`
- **Updated CI docs**: Added GitHub Actions lint workflow info to
`ci.rst`
- **Fixed broken links**: dead tutorial links in `pass_infra.rst`,
`gallery/` → `docs/how_to/tutorials/`, `how-to/index.rst` →
`how_to/dev/index.rst`, `discuss.tvm.ai` → `discuss.tvm.apache.org`
- **Updated overview**: TensorFlow → ONNX in supported framework list,
AutoTVM → RPC in security docs
