This CL adds constants that can be defined in the module scope:
const kConstexprConst: constexpr int31 = 5;
const kIntptrConst: intptr = 4;
const kSmiConst: Smi = 3;
They are implemented by generating "mini-macros" that return the
expression on the right-hand side of the assignment.

This moves the entire code generation phase (including code emission
into the native module) into the background task. The code manager is
fully thread safe by now and there are no Isolate-bound steps anymore.
The only step remaining on the foreground task is publishing the fully
finished code to other threads via {NativeModule::PublishCode}.

This patch adds a variant of EmbedderGraph::AddEdge() which
allows the embedder to specify the name of an edge. The edges
added without name are element edges with auto-incremented indexes
while the edges added with names will be internal edges with
the specified names for more meaningful output in the heap
snapshot.

With ReadOnlyRoots and GetIsolate on JSReceiver, we can remove almost
every isolate parameter from <Object>::Print. The remaining ones, like
Map, are special-caseable for read-only maps, and as a result we can
remove isolate parameters from <Object>::Print entirely.
This patch also opportunistically cleans up a few places where isolates
were only needed for Object::Print, such as TransitionAccessors and
DescriptorArrays.

Specifically the common bug like
new Promise((res, rej) => {

throw new Error("something")
});
where the error is silently swallowed by the Promise constructor without
the user ever noticing can be caught via this hook.

Instead of creating a separate code object per exported function, we
can share the code per signature, and load the function index from the
{WasmExportedFunction} object which is being passed as an argument
anyway.
This greatly reduces instantiation time for modules with a lot of
exports.
As a next step, we could even share the code across instances, or (with
more work) across isolates.
