buffer: mark pool ArrayBuffer as untransferable by addaleax · Pull Request #32759 · nodejs/node

@addaleax

This removes a footgun in which users could attempt to transfer the
pooled ArrayBuffer underlying a regular `Buffer`, which would lead to
all `Buffer`s that share the same pool being rendered unusable as well,
and potentially break creation of new pooled `Buffer`s.

This disables this kind of transfer.
