Since {Handle<T>::location()} just returns the value of
{HandleBase::location()}, we can just publicly expose the latter and
save some compile time and object file size.

Provide a global memory controller used to compute limits for combined
on-heap and embedder memory. The global controller uses the same
mechanism (gc speed, mutator speed) and growing factors as the regular
on-heap controller.

Rely on V8's mechanisms for configured state that stops shrinking the
limit.

Reland:
- API fixes with overrides and default versions.
- Fix of depending on uninitialized values when using the old API.
- GCTracer: Fixed issue in speed computation.
- GCTracer: Added unittests.

This reverts commit 5e043f27.

Add an {ObjectRef} class to Handle which is returned by {operator->}.
Before, it returned {T} directly, and then used {T::operator->} for
the chained {operator->}.
As a drive-by, this CL also removes {HandleBase::operator*} and
implements this in {Handle<T>} directly.

KeyedAccessStoreMode is used when creating store handlers to determine
which cases to handle (ex: handle cow, grow) and hence choose an
approriate builtin. It is also used to specify elements kind transitions
which is used when computing ic transitions. The store mode and the
transition mode are independent of each other and it would be cleaner to
use different enums to represent them. This also reduces the total number
of cases in each enum.

This method is rarely used, and has several problems:
1) It CHECKs that the value is not undefined, then creates a
   {Handle<T>} which again DCHECKs that the value is of type {T}.
2) It is called on a raw {FixedArray} but returns a handle.
3) It is often used when no handle is actually needed, adding
   unnecessary overhead.
4) It adds complexity and hides actual checks and handlification.

This CL removes that method, replacing some uses by explicit CHECKs (in
tests) and relying on the DCHECKs in the casts otherwise.
