src: allocate Buffer memory using ArrayBuffer allocator

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@f61bae3440. It should
render their downstream patch unnecessary.
