Nlog: Mark RequiredParameterAttribute with MeansImplicitUseAttribute attribute

[imanushin]

NLog version: 4.5.0

Platform: .Net 4.7.1

Current issue: ReSharper thinks that properties marked with RequiredParameter are not used, which is completely wrong (see documentation page).

What do I need: help ReSharper to understand, that property (e.g. marked with attribute RequiredParameter) is used from reflection.

Two tasks:

• Update ReSharper Annotations to get the latest supported attributes
• Mark RequiredParameterAttribute with MeansImplicitUseAttribute

Yes, that would be great if you could do a PR for the two tasks 👼

Maybe also update DefaultParameterAttribute to be with MeansImplicitUseAttribute

Ok, will apply on these attributes first (will try on the next weekends). Then will try to find other attributes for improvement
