Add github actions reporter

[nohwnd]

Summary

Add github actions reporter to improve experience for running tests on GitHub.

Background and Motivation

Running tests on GitHub actions is lacking a nice reporting experience that would work out of the box.

Proposed Feature

Add extensions to MTP / dotnet test to show test failures, outputs and summary that can be viewed on github actions.

Refer to microsoft/aspire#8811 (comment) and https://github.com/Tyrrrz/GitHubActionsTestLogger

Alternative Designs

[Evangelink]

Closing as GitHubActionsTestLogger now supports MTP.
