bazel info doesn't work with host_platform using @foo//:bar labels

### Description of the bug:

In Bazel 9.x `--incompatible_use_plus_in_repo_names` flipped, and bazel info inherits `build` options form the .bazel rc.
This means that if we provide our own host plaform from our own extension bazel can nolonger reference it unless we use a fully resolved repo name.

### Which category does this issue belong to?

Core

### What's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.

[bazel-info-repro.zip](https://github.com/user-attachments/files/28591189/bazel-info-repro.zip)
This contains a very minimal reproduction.
```
# FAILS — apparent label, bazel info resolves to @@host_platform (legacy format)
bazel info bazel-bin
→ ERROR: Repository '@@host_platform' is not defined

# SUCCEEDS — apparent label works fine for build commands
bazel build //...

# SUCCEEDS — explicit canonical label bypasses the broken mapping
bazel info bazel-bin --host_platform=@@+host_platform_ext+host_platform//:host
```

### Which operating system are you running Bazel on?

windows

### What is the output of `bazel info release`?

release 9.1.0

### If `bazel info release` returns `development version` or `(@non-git)`, tell us how you built Bazel.

### What's the output of `git remote get-url origin; git rev-parse HEAD` ?

Start with the attached bazel-info-repro.zip and compare the failing `bazel info bazel-bin --host_platform=@foo//:bar` behavior with the successful build command and canonical label. Use the bisected commit 632540df12a1fa96b6db3d8f5cb45a9255c0a903 as the entry point; done means bazel info resolves the apparent label from the .bazelrc without requiring the fully resolved repository name.
