Change the unittest runner to no longer uncondtionally set up a default
platform in the "environment", but to instead make platform set-up part
of the "mixin" framework for test fixtures.
Requires modifying some tests that expect the platform to be available,
and all flag implications resolved, before the mixin constructors run.
We still keep the environment for setting up the process for cppgc. This
process setup can only be done once per process, so it can no longer use
the platform -- that's ok though, the page allocator used by cppgc's
process initialisation doesn't have to be the same as the platform's so
we can just pass in a separate new one.

The hello world sample needs to initialize V8's default platform in case
it is not built as stand-alone example.

Both sample are essentially the same up to string constants since
cppgc's default platform started using libplatform.
The only diff between the sample is whether we call
v8::V8::IntializePlatform or cppgc::InitializeProcess.
Drive-by: replace CPPGC_BUILD_IN_V8 with CPPGC_IS_STANDALONE which is
more descriptive.

Unified heap support in V8 requires having another (at least internal)
heap that implements a unfied garbage collection strategy. This will
not re-use the already existing cppgc::Heap because there should be no
way in creating such a heap externally or scheduling stand-alone
garbage collections.
In order to have a common token, this CL introduces AllocationHandle
which can be passed to MakeGarbageCollected to allocate C++ objects.
V8 (soon) and the stand-alone heap both have methods to retrieve such
a handle.
This works around a problem with creating diamond class hierarchies
when a base class would be exposed on the public API level.
Fast paths for Blink are still possible because allocation handles can
be cached the same way (e.g. global, or TLS) as a heap can be cached.
