Original commit message: [api] Add `Isolate::GetArrayBufferAllocator()` This allows non-monolithic embedders to always allocate memory for ArrayBuffer instances using the right allocation method. This is based on a patch that Electron is currently using. Refs: https://github.com/electron/electron/blob/1898f9162073910c05958295c612deec6121a892/patches/common/v8/array_buffer.patch Change-Id: I39a614343118a0594aab48699a99cc2aad5b7ba9 Reviewed-on: https://chromium-review.googlesource.com/c/1462003 Reviewed-by: Yang Guo <yangguo@chromium.org> Commit-Queue: Yang Guo <yangguo@chromium.org> Cr-Commit-Position: refs/heads/master@{#59697} Refs: v8/v8@d3308d0 PR-URL: nodejs#26207 Reviewed-By: James M Snell <jasnell@gmail.com> Reviewed-By: Joyee Cheung <joyeec9h3@gmail.com>
This enables us to identify whether we are using an allocator that we know more about than what the generic `ArrayBuffer::Allocator` API provides, in particular whether it is `malloc()`-compatible.

If the `ArrayBuffer::Allocator` used to create `ArrayBuffer`s in the current `Isolate` is not a Node.js `ArrayBufferAllocator`, we cannot know that it is `malloc()`-based, an in particular it might not be compatible with the `ArrayBuffer::Allocator` on the receiving end of the connection.

Add a subclass of `ArrayBufferAllocator` that performs additional debug checking, which in particular verifies that: - All `ArrayBuffer` backing stores have been allocated with this allocator, or have been explicitly marked as coming from a compatible source. - All memory allocated by the allocator has been freed once it is destroyed.

Add a RAII utility for managing blocks of memory that have been allocated with the `ArrayBuffer::Allocator` for a given `Isolate`. PR-URL: nodejs#26207 Reviewed-By: James M Snell <jasnell@gmail.com> Reviewed-By: Joyee Cheung <joyeec9h3@gmail.com>
Always use the right allocator for memory that is turned into an `ArrayBuffer` at a later point. This enables embedders to use their own `ArrayBuffer::Allocator`s, and is inspired by Electron’s electron/node@f61bae3440e. It should render their downstream patch unnecessary.
