Subject: [PATCH] build: publish ts-api-guardian rule in the npm package
 (#29977)

With this change downstream users will no longer need to build ts-api-guardian from source as now the bazel rule is available in the npm package.

This can be used by installing ts-api-guardian as a devDependency and changing the load syntax from:
```
load("@angular//tools/ts-api-guardian:index.bzl", "ts_api_guardian_test")
```

to:
```
load("@npm_ts_api_guardian//:index.bzl", "ts_api_guardian_test")
```

**Note**: downstream users should also clean their `WORKSPACE` and remove the dependencies of angular workspace.

PR Close #29977
