[VM] Extend subtype-test mechanism with support for generic methods

Until now the subtype-test cache mechanism did not work (i.e. could
return the wrong result) for partially instantiated generic closures.

Additionally, closures which close over generic methods were always
handled in runtime.  This caused a servere performance regression for
any code hitting this (e.g. code which uses `package:stack_trace`).
