Introduce zero invocations in test templates and parameterized tests

[nskvortsov]

Add a flag to ParameterizedTest to control arguments requirement. This allows users to explicitly opt out from validation of arguments set count and silently skip a test if no arguments are provided

In general, support TestTemplateInvocationContextProvider returning zero invocation contexts. Such providers must override new interface method to indicate that the framework should expect "no context returned"

Resolves #1477
