Subject: fix(ext/ffi): Use BufferSource for FFI buffer types (#16355)

Potential fix for type-code mismatch in FFI buffer types. The code
supports ArrayBuffers, but types only reflect TypedArray support.

There's also an existing type for this sort of stuff: `BufferSource`.
(Although, it uses `ArrayBufferView` which doesn't actually connect with
the TypedArray interfaces specifically, but it's just a type inheritance
difference and nothing more.)
