MTP: Add command-line parameters for settings in coverage configuration file #199

Summary

Enable overriding the coverage settings from a configuration file on the command line, similarly to what's possible with VSTest.

Background and Motivation

To make coverage work with SonarCloud, we need different settings. Not everything listed at https://learn.microsoft.com/en-us/dotnet/core/additional-tools/dotnet-coverage#settings and https://github.com/microsoft/codecoverage/blob/main/docs/configuration.md can be overridden from the command line. Therefore, we need to maintain multiple almost-similar configuration files for coverage settings, depending on which tool consumes the coverage data and where the tests execute.
