Configure advanced codeql.yml scanning

It appears GH doesn't recognize our CodeQL pipeline and attempts to run
its own default version.
Rename the workflow to conform to what GH expects of the standard
"advanced setup" for CodeQL, with some minor updates:
 - run on `release/*` branches
 - use the recommended job permissions
 - explicit `manual` build mode
 - use `c-cpp` instead of `cpp`
 - add a `codeql-config` file to ignore the test and vendor directories

Based on recommendations here, which simple create the appropriate
workflow:
