[Built-in analyzer] Build depends on an environment variable

[ladipro]

Background

This issue tracks one of the BuildCheck analyzers we would like to ship in-box with MSBuild.

Goal

Implement an analyzer with the following rule: No implicit property derived from an environment variable is used during the build.

Notes

Depending on the environment leads to build reproducibility problems. Properties should instead be passed to MSBuild explicitly on the command line with /p.
