[CK] Re-enable HIPRTC codegen tests for all CK PRs.

## Motivation

At the time when we introduced the smart test filter to only build and
run tests affected by the PR changes, we disabled the client examples,
which required full CK build, and also the hiprtc tests that were
grouped with the client examples. This caused a few PRs to sneak through
that caused the hiprtc compilation to fail.
By restoring the hiprtc tests in all PRs, we should close this gap.
