feat(ci): add codecov checks for idlc (#852)

This is this initial PR; after this merges with main, we should start
seeing coverage status checks on subsequent PRs.

Initially, this has the following thresholds:

- No more than a 1% drop in coverage overall.
- At least 90% coverage on any new code in a patch
