Patterns for `--deleted_packages`.

### Description of the feature request:

I propose a pattern (or a prefix match) for `--deleted_packages`.

```
--deleted_packages=foo/bar/...
```

Note this is different than .bazelignore/ignore_directories(), because it does not restrict glob().

### Which category does this issue belong to?

Configurability

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

This is useful anytime you want Bazel to skip interpreting BUILD files, but not ignore other contents.

---

It can be useful to reach across every file in the repo.

1. Linting
2. E2E tests on Bazel itself

To do this, I create a repo that symlinks the workspace, and then use `--deleted_packages` to effectively deleted all the BUILD files from the repo. I can add a root BUILD to the repo that can glob() anything.

The `--deleted_packages` winds up quite long.

---

Another case is adding code from other projects without having any part of their BUILDs affect things. Either because they are poorly written, or they are for another system (Buck).

Being able to *delete all package definitions below a certain point -- while still having access to the files* -- is a valuable escape hatch.

Start by tracing how the --deleted_packages option is parsed and how deleted packages affect BUILD-file interpretation. Define the behavior for a prefix pattern such as foo/bar/... while preserving access to other files and glob() results; no specific files or tests are named in the issue.
