[BuildCheck Suggestion]: Well-known properties applied as item metadata

### Summary

It'd be great if we could scan for some patterns where a property (that we know about) is set instead as item metadata.

### Background and Motivation

"Things" in MSBuild are properties, items, or metadata on specific items. But if you hear "set X", it's hard to know which category X is in, and easy to make mistakes.

### Sample issue or antipattern that the check should be flagging

An anonymous dev hit some trouble with a NuGet package and tried to fix it by doing this

```xml

true

```

Looks convincing! But it's wrong, because `CopyLocalLockFileAssemblies` is a _project property_, not a per-package setting. Sure would be nice if MSBuild could help.
