Generate exact JS buffer types for exact IDL buffer arguments instead of widening them to BufferSource or ArrayBufferView. This fixes cases like TextEncoder.encodeInto(), whose IDL requires a Uint8Array destination. Previously the generated binding accepted any BufferSource, so DataView, other typed arrays, and ArrayBuffer-backed values were let through. With exact conversion, those are rejected at the binding layer as expected.
