This behavior changed recently. SharedArrayBuffers should not be put in the
transfer list, because they are not detached, and that is the meaning of being
in the transfer list.
This is the V8 side of the change, the Blink side will come next.

Add a parameter to AddMessageHandler to select which error levels to receive, using a mask (default being just errors, i.e. the current behavior).

The current logic in Isolate::GetLocationFromStackTrace just ignores
wasm frames, making the computed location point to the first javascript
frame, like this:
test.js:17: RuntimeError: divide by zero
module.exports.main();
^
RuntimeError: divide by zero
at main (<WASM>[1]+5)
at test.js:17:16
This CL not only fixes the location to point to the top-most wasm
frame, but also exposes to the embedder that the script of that location
is a wasm script, allowing for custom printing of wasm locations.
The Shell::ReportException method now checks for this flag, and prints
wasm locations like this:
<WASM>[0]+5: RuntimeError: divide by zero
RuntimeError: divide by zero
at main (<WASM>[0]+5)
at test/message/wasm-trap.js:15:16

Aside from the default snapshot, there is no need for additional context
snapshots to have the ability to replace the global proxy and global object
after deserialization. Changes include:
- Changes to the API to better distinguish default context snapshot from
additional context snapshots.
- Disallow global handles when creating snapshots.
- Allow extensions when creating snapshots.
This solves the issue of not being able to having accessors and interceptors on
the global object of contexts to be serialized.

Some accessors requires little to no computation at all, its result can be
cached in a private property, avoiding the call overhead.
Calls to the getter are translated into a cheap property load.

This patch removes TracingCategoryObserver API and moves the creation of
observer inside platform initialization, by assuming that either
Platform::AddTraceStateObserver is implemented correctly to add observer to
tracing controller that implemented by embedders, or default tracing controller
has already been set up and attached to platform before
v8::V8::InitializePlatform is called.

This patch implements TracingCategoryObserver to set global flag when a V8
specific category is enabled. Previously, we set a global flag each time when we
encounter a top level trace event, and use it as a global check. With this
patch, we can set a group of flags when tracing is enabled; besides, we make
V8 tracing feature use V8 flags instead of defining its own flag in a messy way.
With this patch, whatever V8 flag we want to imply in tracing, we define another
integer flag, and the original V8 flag will set it to 0x01 when passing by
commandline, tracing will set it to 0x10 when we start tracing and reset the bit
when we stop tracing.

This is useful for things that don't ever change, but we don't want to
eagerly compute the result.
Doing this from the embedder is difficult, using DefineOwnProperty would
read the property to get the property descriptor, creating an endless
recursion.

Since the public API for deserialization is now just DeserializeOrCompile,
we can trickle down the wire bytes to the deserialization logic, and
avoid the need for duplicating the wire bytes when serializing.

This incorporates recent feedback:
- simpler deserialization API by dropping the std::unique_ptr.
The only purpose there was communicating to the caller that they
own the buffer, and that the deserializer won't delete it. The new
design communicates that through a naming choice.
- renamed *UncompiledBytes to *WasmWireBytes

This is a re-land of https://codereview.chromium.org/2393303002/ with
an additional call to DisposeModuleEmbedderData() added to fix lsan failures.
Unifies the approaches used for storing the specifier -> module mapping
and the module -> directory mapping, using std::unordered_maps for both
and storing them per-Context.
This requires adding a method to the v8::Module API to get a hash code
for a Module, but allows slimming down the API in return: gone are
SetEmbedderData/GetEmbedderData, along with the fourth argument
to ResolveModuleCallback.
Besides a simpler API, this allows d8 to get closer to the HTML loader,
which requires each Realm to have a persistent module map (though this
capability is not yet exercised by any tests).
