Some static-analysis support

[SteveL-MSFT]

Summary of the new feature / enhancement

Instead of hitting a run-time error, it would be useful to have some static analysis be performed. I do wonder if it should be part of whatIf or separate since whatIf will already handle some of it:

• schema validation of properties
• dependsOn circular loops (although this is caught early on during execution)
• [reference()] w/o explicit dependsOn
• [resourceId()] that doesn't exist (think typo)
• invalid functions or function arguments

Proposed technical implementation details (optional)
