Move softmax matcher and ErrorCheckingTrackingListener out of iree-dialects (#24466) (#24543)

Closes #24466 (retire the
`llvm-external-projects/iree-dialects`
dependency). Relocates the last two pieces of code that still depended
on the NFC directory. Finishing Tasks 1 & 4.

- **[GlobalOpt] Reimplements the softmax matcher within
`GlobalOptimization/`. Adds `arith.maximumf` support to account for SHLO decompositions.
- **[Codegen] Move ErrorCheckingTrackingListener** into
`Codegen/Common/` and de-register `StructuredTransformOpsExtension` from
`CommonDialectRegistration` and `Interfaces`. Continuation of #24500.
- Removes llvm-external-projects/iree-dialects as a whole

## Testing

Built and lit tested locally on Windows 11 + MSVC 14.44 (VS 2022
Community), Ninja, CMake 3.29, Release with assertions,
`IREE_TARGET_BACKEND_LLVM_CPU=ON`. All changed files compile cleanly.
The softmax lit test
`compiler/src/iree/compiler/GlobalOptimization/test/raise_special_ops.mlir`
passed. all three variants (`@softmax`, `@softmax_no_rcp`,
`@softmax_broadcast`) match correctly through the relocated
`makeSoftmaxMatcher`.
