Bohan Hou bb6f8aec55 [TIRx] Post-bringup follow-ups: op-dispatch, namespaces, launch bounds, gemm-async, backend reorg (#19757)
This PR batches several post-bringup TIRx follow-ups, rebased onto
current `main`.

### Changes
- **op-dispatch**: per-call exec scope via `Tx.<scope>.op`; remove
`ExecScopeStmt`
- **namespaces**: split TIRx op namespaces; remove tile-primitive kind
attrs
- **codegen**: support explicit CUDA launch bounds
- **gemm-async**: support contiguous-axis (K-major) operand slicing
- **backend reorg**: move in-tree GPU backends out of core into
`src/backend/<target>/` and `python/tvm/backend/<target>/`
(codegen/runtime/op), with the corresponding `CMakeLists.txt` /
`cmake/modules` and include-path updates

### Testing
- Builds with `USE_CUDA=ON` / `USE_LLVM=ON`
- The TIRx Python test suite (`tests/python/tirx/`) passes locally
