Support for reproducible builds

[clairernovotny]

Describe the Feature

Enables reproducible builds to improve supply chain security and enable better debugging experience.

Is your Feature Request related to a problem?

Currently cannot easily step into library code in the debugger. Also cannot determine if code in package matches code in the repo.

Proposed Solution

Add support for reproducible builds as a best practice. It can be done by either dropping the DotNet.ReproducibleBuilds as a build-time package in a Directory.Build.props file or by manually adding the required properties and dependencies. See https://github.com/dotnet/reproducible-builds for details.

Describe alternatives you've considered

There are none.

Additional Context

I wrote a blog post that describes how to produce these packages, and another that shows the improved debugging experience.

Environment

This requires using the .NET SDK 5.0.300 or / MSBuild 16.10 later to build.

Might be related to aws/aws-lambda-dotnet#968 since reproducible builds also adds SourceLink dependencies for all repo types (refer https://github.com/dotnet/reproducible-builds#dotnetreproduciblebuilds-nuget-package). Needs review with the team.
