[Feature]: Suppress VSTHRD200 on methods with BaseTestAttribute/TestAttribute

[radmorecameron]

Problem Statement

VSTHRD200 has suggestions for adding Async at the end of all async methods. This is good for more methods but isn't ideal for tests. It'd be great if it can be suppressed

Proposed Solution

Add an analyzer to suppress VSTHRD200

Alternatives Considered

MSTest and XUnit have suppressions for this:
MSTest (MIT): microsoft/testfx#2926
XUnit (apache 2.0 license): xunit/xunit.analyzers@4f2297b

I think it would be possible to copy one of their implementations with minimal changes as long as it's properly attributed
