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.

Add new types for function data for SharedFunctionInfo, for uncompiled

kPromiseResolveAfterResolved
which are used to detect (and signal) misuse of the Promise constructor.
Specifically the common bug like

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.

Now that ReadOnlyRoots is used everywhere to access the read-only roots,
this makes the Heap accessors for such roots private.
It also adds tests that the roots reachable from ReadOnlyRoots are all
in RO_SPACE as well as tests that the roots still publicly accessible
from Heap are not in RO_SPACE. There's a white list in the file for
the few roots where the root pointer itself can change. (For instance
materialized_objects points to empty_fixed_array to start with before
before later pointing to a mutable array).
Also fixes up new use of heap->empty_fixed_array() in elements.cc added
