fix: compile js-samples as part of tests

[i2amsam]

Following up from #1847 I realized that the samples are not getting compiled in CI to test for regressions. This adds a setup and build step to the samples that start with C. If this looks good, I'll include the other samples too.

@pavelgj do we need to add "Build Samples" as a new blocking check in the repo config? Seems like maybe that config is out-of-date, only 3 of the 8 tasks are required to pass for submit.
