This is a reland of 7dbfec50e3, now that
pdfium has been updated to avoid libfuzzer build failures. I've tested
this change locally in pdfium xfa and non-xfa builds.
The calls in chromium were removed in https://crrev.com/c/865160,
while pdfium was updated in https://pdfium-review.googlesource.com/c/pdfium/+/23270.

Before this, only the [[ProxyHandler]] was set to null during revocation
of the Proxy through either the v8::Proxy::Revoke() or the
Proxy.revocable() API. To be consistent with the spec, the Proxy's
target is set to null as well. This change should not be observable
through JS, since the check for if the Proxy is revoked should always
use the handler. But the changed value is exposed through the public
v8::Proxy::GetTarget() API, which is used by the inspector API and
Node.js.
Also included is a much more comprehensive test for Inspector's support
for Proxy, which prior to this commit did not work as intended.

Now that we have an API to request code cache, we want to decouple
compilation from serialization. As a first step, we will add CompileEager
option (used when we want to produce full code cache) and
DeferredProduceCodeOption to NoCacheReason. This is so that we can
properly bucket the compilation time and collect statistics about the
cache behaviour. Once, blink and node start using the new API, we can
remove the code to produce code cache from the compilation.

We collect instance type statistics in FatalProcessOutOfMemory into an
array, which is allocated to the max instance type value. While we want
to leave space to ensure new instance types do not affect constants in
the API, we can be more frugal.
We currently serialize 350 maps into the startup/context snapshot. Even
if we assign a distinct instance type to each of these maps, we would
still have more than enough to spare with this change.

- protocol client can fetch Runtime.StackTrace by

- externalParent field is added to Debugger.paused event, it may

- V8Inspector::storeCurrentStackTrace captures current stack trace
and returns V8StackTraceId for embedder this id can be used as

trace captured between these calls will get passed external stack
trace as external parent. These methods are designed to be called
on different debuggers. If async task is scheduled and started on

on debugger with given id,
- protocol client can fetch Runtime.StackTrace by
Runtime.StacKTraceId using Debugger.getStackTrace method,
- externalParent field is added to Debugger.paused event, it may
contain external parent stack trace,
- V8Inspector::storeCurrentStackTrace captures current stack trace
and returns V8StackTraceId for embedder this id can be used as
argument for V8Inspector::externalAsyncTaskStarted and
V8Inspector::externalAsyncTaskFinished method. Any async stack
trace captured between these calls will get passed external stack
trace as external parent. These methods are designed to be called
on different debuggers. If async task is scheduled and started on
one debugger user should continue to use asyncTask* API,
- Debugger.enable methods returns unique debuggerId.

Add another entry to the NoCacheReason enum, reporting that the chromium
ScriptResource has no cache handler.
Also, the amount of chromium-specific entries in this enum is getting
too high. So, added a TODO for removing them -- possibly in the future
we want to do this no-cache reason logging in Chromium after all,
propagating isolate cache hits and consume failures back up the API with
an out parameter.

Persistent handles are always independent these days. Users should mark
weak handles as active using MarkActive if they want to keep weak
handles that are otherwise unreachable alive across scavenges.
