Instead of one big test which tests multiple functions, split the unit
test into multiple smaller tests.
Also, use TestWithZone instead of TestWithIsolate, because the isolate
is never used.

As sandboxed pointers are now default-enabled when the sandbox is
enabled, it is no longer possible to deactivate the sandbox at runtime.
This CL therefore removes all the logic that was required to support a
sandbox that could be disabled at runtime, moves the initialization of
the sandbox into V8::Initialize, and deprecates V8::InitializeSandbox.
This change also makes the sandbox initialization deterministic if
FLAG_random_seed is supplied.

The operator with raw pointer allows us to avoid Member decompression,
which is more expensive than compression. It's also quite frequently
called (e.g. in HeapHashSet::find()).
The existing operator
template <...>
bool operator==(const Member<T1>&, const Member<T2>&);
was not called for
GCed* raw = ...;
member == raw;
because the compiler wouldn't deduce `T2` in `const Member<T2>` as
`GCed` when the initializer expression `raw` is of different type
(`GCed*`).
