1. [[exceptions] Unify pending and scheduled exceptions](https://chromium-review.googlesource.com/c/v8/v8/+/5050065)
Reset no longer clears exception if it was rethrown. The test had to be adjusted for the same.
2. [[api] Allow passing CppHeap on Isolate creation](https://chromium-review.googlesource.com/c/v8/v8/+/4989254)
`AttachCppHeap` was deprecated but the alternative of passing `CppHeap` via Isolate CreateParams hard crashes (SIGSEGV). There are no tests for this in V8 and it seems the [Chromium CL](https://chromium-review.googlesource.com/c/chromium/src/+/4992764) is also crashing. For now I've just suppressed the deprecation warning until the crash is fixed in V8.
3. v8::Serializer impl must not throw more than one exception.
I changed `get_shared_buffer_id()` to not throw and return `None`. V8 internally calls data clone error when it's the SAB is not clonable.
Other changes:
- `v8::ScriptCompiler` size increased by 3 words with `v8::ScriptCompiler::CompilationDetails`.
- `v8::ObjectTemplate::SetAccessor` & `v8::ObjectTemplate::SetAccessorProperty` signature changed and also deprecated.
- `v8::Context::SetContinuationPreservedEmbedderData` deprecated. Use `v8::Isolate::GetContinuationPreservedEmbedderData` instead.
- `GetStalledTopLevelAwaitMessage` deprecated. Use `GetStalledTopLevelAwaitMessages` instead.
- `v8::Isolate::AttachCppHeap` deprecated. Set the heap on Isolate creation using CreateParams instead.
- `v8::ScriptOrigin` deprecated. Use constructor without the isolate.
- `v8::SnapshotCreator` is deprecated. Use the version that passes CreateParams instead.
- `v8::Isolate` assertion failures.

Add v8::ValueSerializerImpl::{has_custom_host_object,is_host_object}
equivalents for v8::ValueSerializer::Delegate::{HasCustomHostObject,IsCustomHostObject}.
This enables serializing custom host objects without embedder fields.
