Update Kover to 0.9.0-RC, Add Coverage Report to CI, and Consolidate Workflows

[matt-ramotar]

This PR is:

• Updating Kover to 0.9.0-RC
• Generating coverage report on check and uploading to Codecov
• Consolidating CI workflows

My goal is to get our coverage above 90%. Will start chipping away at uncovered code after this merges.

You're on an old version of Kover, and they made some improvements, including better detection of certain constants patterns that don't need coverage.

Recommend updating to latest stable (or check out rc build), as well as looking into any central exclusions that would make sense for the project wide.

[tyvsmith]

Is the coverage file being treated as generated code in PR review process already? If not, that should be added to the .gitattributes file so it doesn't create additional noise.

[matt-ramotar]

Good callout, thanks. We were previously checking it in. Removed coverage reports from the repo, updated our .gitignore, and modified our workflows accordingly.
