Original commit message:
[api] add Isolate::Deinitialize() and Isolate::Free()
This allows embedders to mirror the isolate disposal routine
with an initialization routine that uses Isolate::Allocate().
```
v8::Isolate* isolate = v8::Isolate::Allocate();
// Use the isolate address as a key.
v8::Isolate::Initialize(isolate, params);
isolate->Deinitialize();
// Remove the entry keyed by isolate address.
v8::Isolate::Free(isolate);
```
Previously, the only way to dispose the isolate bundles the
de-initialization and the freeing of the address together in
v8::Isolate::Dispose(). This is inadequate for embedders like
Node.js that uses the isolate address as a key to manage the
task runner associated with it, if another thread gets an
isolate allocated at the aligned address before the other
thread finishes cleanup for the isolate previously allocated
at the same address, and locking on the entire disposal can
be too risky since it may post GC tasks that in turn requires
using the isolate address to locate the task runner. It's a
lot simpler to handle the issue if the disposal process of
the isolate can mirror the initialization of it and split
into two routines.

Original commit message:
[api] add v8::Isolate::GetDefaultLocale()
This allows embedders to query the default locale used by Intl
APIs.
This information is already available to user land via
Intl?.Collator().resolvedOptions().locale, the issue with this
is that it's a lot slower and requires dynamic access to Intl
API, which is subject to patching and prototype pollution so it's
not as reliable for embedders than having a V8 API to query
the default locale directly.

[api] Add v8::ScriptCompiler::CachedData::CompatibilityCheck()
This patch adds a new API v8::ScriptCompiler::CachedData::CompatibilityCheck()
in order to allow embedders to check if the code cache can be used in
the current isolate without looking up for the source code. It also returns more detailed reasons about why the code cache cannot be used
when it's bound to be rejected. This makes it possible to enforce
portability checks in case code code becomes CPU-dependent in the
future.
