This adds an {AccountingAllocator} to the {WasmEngine}, separate from
the allocator used per Isolate. It is in preparation of being able to
share engines across multiple Isolates. For now we just add up the
stats from both allocators until a public API for the engine becomes
available.

This introduces a second factory method for allocating new module
objects that are based on existing native modules which are potentially
shared between multiple Isolates.

This is a first set of test cases for sharing an {WasmEngine} and the
contained {WasmCode} between multiple Isolates. Currently this can only
be done using internal API methods on the Isolate, an external API that
is usable by embedders does not exist yet.
