CA1416: Consider supporting guard clauses like IsThreadStartSupported

Consider supporting guard clauses like IsThreadStartSupported in Platform compatibility analyzer

I'd have hoped the analyzer would be able to understand the guard clauses like IsThreadStartSupported just as the linker can. Is that not possible?

@buyaa-n could you please give a little more detail about the issue? As far as I understand the idea is to fix a false positive with the rule CA1416, is it more global? If not, maybe the title should state the rule and the label might be False-Positive instead of Enhancement.

It is not a fix for a false positive, it would be an enhancement for the analyzer to support this scenario. Yes, it is related to CA1416 only, updated the title, thanks!
