Review SDK names and setup

[Evangelink]

Let's review the following points before we ship the feature complete preview:

• is this https://github.com/microsoft/testfx/blob/main/src/Package/MSTest.Sdk/Sdk/Runner/ClassicEngine.targets#L20 needed? It seems we could do without it.

• make it possible to opt-out from analyzers (e.g. https://github.com/microsoft/testfx/blob/main/src/Package/MSTest.Sdk/Sdk/Runner/ClassicEngine.targets#L61) <EnableMSTestAnalyzers>

• review engine names: use the standard native aot knob used by the runtime. <PublishAot>true</PublishAot>
