[HLO Componentization] Populate hlo/testlib sub-component (Phase II).

This CL takes care of
1. Migrating external projects dependencies from

```
tensorflow/compiler/xla:test
tensorflow/compiler/xla:test_helpers
tensorflow/compiler/xla/service:pattern_matcher_gmock
```

to `tensorflow/compiler/xla/hlo/testlib:*`
