Michael Lippautz 143e6a74d8 cppgc: Check for correct base class inheritance 
The only valid way to define a GCed type T is by inheriting from
GarbageCollected<T>. Since this is prone to typos (see tests), add a
simple check that covers most interesting use cases.

The static assert covers
  A -> B -> GarbageCollected<C>

The static assert does not cover
 A -> B -> C -> GarbageCollected<B>

(In order to do so, we would need __direct_bases() support which is
not yet available for C++.)

C++ Garbage Collection

This directory provides an open-source garbage collection library for C++.

The library is under construction, meaning that all APIs in this directory are incomplete and considered unstable and should not be used.
