Make `@ResourceLock` applicable to class templates (its invocations, that is)

[t-o-n-y-p]

Hi all. I'm in the process of migration from 5.11.3 to 6.0.0 right now, and I'm trying to implement class templates instead of test class inheritance. I face a loss of functionality regarding resource locks.

Right now, I'm able to do a @ResourceLock on multiple parent classes which share a resource, and all the child classes respect that lock. With class templates, I can't lock a resource for them the same way, and I wish I could apply a resource lock to invocations of a class template the same way I do now for my child classes.
