As `tools/mod` also contains the `go.mod` file. We should add it to the
`module_dirs` variable, so that when executing `./scripts/fix.sh`, the
proper checks and fixes can be applied.
To address the issue of broken unit tests and code coverage due to the
directory's lack of Go code, we've introduced a new doc.go file. This
file acts as a placeholder, enabling tools like golangci-lint and
go test to function correctly.

Discovered when working on https://github.com/etcd-io/etcd/pull/18575
The directories are checked against the following:
- Command: `find . -type f -name go.mod -exec dirname {} \;`
- Output:
```
./etcdutl
.
./tools/testgrid-analysis
./tools/rw-heatmaps
./tools/mod
./etcdctl
./tests
./server
./api
./client/internal/v2
./client/v3
./client/pkg
./pkg
```

Replace ./scripts/install_tool.sh with `gobin`, such that we have
consistent handling for all tools needed for build and consistent
versioning within ./tools/mod/go.mod.
Side changes:
- Expose /scripts/fix.sh that fixes formatting and bom across modules
- Expose *.sh variants of scripts like build and ./test (first step
towards replacement).
- Make stderr output of commands explicit and make commands use
different color than callouts.
