## Summary Restructure TVMScript to be dialect-agnostic at the script-core layer while letting each extension dialect (TIRX, Relax) own its own per-dialect script subtree. IR is below script in the dependency stack and is NOT a peer dialect — its script handlers stay in the shared core. This PR folds together two coupled refactors that were initially opened as separate PRs (#19478 and the original #19479); they share rename / relocation surface so they ship as one cohesive change. ## What this PR does ### Per-dialect script subtree (originally #19479) - Moves per-dialect printer + builder from `src/script/{printer,ir_builder}/{tirx,relax}/` to `src/{tirx,relax}/script/{printer,builder}/`. - Tightens `src/script/*.cc` CMake glob to the dialect-free core. - Refactors `IRBuilder::DeclFunction` to dispatch via FFI registry (`script.ir_builder.decl_function.<type-key>`); removes cross-dialect includes from the shared core. - Adds `tvm.script.register_dialect` API + `__getattr__` + a `sys.meta_path` finder for Python-side dialect discovery. In-tree dialects (tirx, relax) registered centrally in `python/tvm/__init__.py`. - Drops the obsolete static re-export shims at `python/tvm/script/{parser,ir_builder}/{tirx,relax}/`. ### Dialect-agnostic printer config (originally #19478) - Relocates `include/tvm/ir/script_printer.h` → `include/tvm/script/printer/config.h` next to the rest of the printer's public surface. The header is not IR-specific. - Renames `TVM_SCRIPT_REPR` → `TVM_REGISTER_SCRIPT_AS_REPR` for clarity (the macro registers Script as the kRepr callback + per-type vtable dispatch). Aligns with the `TVM_REGISTER_*` family. - Drops dialect-hardcoded `PrinterConfig` fields (`tir_prefix`, `relax_prefix`, `show_all_struct_info`, `buffer_dtype`) in favor of a generic `ffi::Map<String, Any> extra_config` keyed by `"<dialect>.<knob>"`. Each call site reads via the templated accessor `config->GetExtraConfig<T>("...", default)`. - Promotes `std::string` config fields to `ffi::String`. After this lands, the script-printer core knows nothing specific about any dialect — new dialects plug in via the registry pattern with zero core edits. Public Python API surface unchanged.
