Relaxing scope rules for genquery()

### Description of the feature request:

Relax the requirement for scopes in some cases, for instance, if we only care about packages.

### Which category does this issue belong to?

Rules API

### What underlying problem are you trying to solve with this feature?

Ability to simulate the command: `bazel query "//...:all" --output package`
I did test that locally in my machine (removing all the scope checks) and it worked without any problem.
```
genquery(
name = "genquery",
expression = "//services/...:all",
opts = [
"--output=package",
],
scope = ["all"],
strict = False,
)
```

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

Microsoft Windows [Version 10.0.26200.5001]

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

7.1.1

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

_No response_

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

_No response_

### Have you found anything relevant by searching the web?

No

### Any other information, logs, or outputs that you want to share?

_No response_

Start with the genquery() scope validation and compare its behavior with the stated bazel query "//...:all" --output package example. Done means package output can be generated without requiring irrelevant scopes, while preserving appropriate validation for other outputs.
