Display labeled code coverage in pull requests

[KeisukeShima]

Related to autowarefoundation/autoware-documentation#2, I would like to add the feature to measure and display code coverage for pull requests to improve review process.

Considerations

• About the reporter, whether to use CodeCov or to create a function to measure and report in GitHub Actions.
• How to specify labels for coverage by label, whether to automatically collect all labels or to specify the labels we want to set.

👍
I think using CodeCov at first is efficient.

@KeisukeShima Can this be closed?
Or will you work on coverage by label in this issue? If so, I think the title should be changed.

I think that getting coverage by label is also part of this issue.
If we need to change the title, how about changing it to Display labeled code coverage in pull request?
