[Nestmates] RFR (S): Support access to VM annotations from nonfindable classes

FTR some time ago I tried a different approach based on access checks 
provided by the module system [1]. It covers broader scope in a uniform 
manner, but also more involved and doesn't fit well existing class 
loading machinery [2].

Best regards,

[2] It does proper access checks very late in the class loading process 
optimistically assuming all annotations are accessible and initiate 
reparsing if any of used ones aren't accessible to the class being loaded.
