Add ReSharper's InspectCode to CI builds

Add ReSharper's InspectCode to CI builds for the following benefits:

• Not require contributors/maintainers to have a ReSharper license
• Maintainer does not have to highlight basic issues & opportunities
• A contributor can review basic issues & opportunities without waiting for maintainer
• Automation of static analysis

Ideally a summary of the code inspection results is published to the PR as a comment with a link to the full report. What would be awesome/nice-to-have is a delta from a previous report on the same PR.
