[cmake] Move inclusion of tools directory up (#11685)
Results in phony rules generated for both tools and Python to refer to
those in tools/ in short form. That is, iree-compile phony target now
refers to tools/iree-compile rather than the one inside _mlir_libs:
```sh
$ rg -e "build iree-dump-module" -e "build iree-lld" -e "build iree-compile" build.ninja
211387:build iree-compile: phony tools/iree-compile
211391:build iree-dump-module: phony tools/iree-dump-module
211397:build iree-lld: phony compiler/bindings/python/iree/compiler/_mlir_libs/iree-lld
```
Fixes #9329.
