dotnet CLI: Create consistent console output mechanism + features

[MiYanni]

Summary

Currently, the dotnet CLI uses a basic Reporter class that is used to output to the console. This is a very basic outputter and doesn't offer any shared logic or functionality for the commands to utilize. We've added other aspects around it to help with code reuse, but we need several mechanisms to kinda "heard the cats" on output from the CLI in general.

High-Level Changes/Goals

• Allow built-in filtering mechanism for different output levels (built-in "verbosity" concept)
• Allow different output formats (machine-readable formats included)
• Allow better support for help text (currently very haphazard, only basic support from S.CL)
• Allow output to include both stdout and stderr
• Review all current command outputs and integrate these consistency features
• QoL: Built-in coloring and resource string support
• Potential: Native recognition of S.CL options (such as verbosity, output formats, help) to work with the features above
• Potential: Consider design for the interactive prompt experience as it relates to output
