update future.{write,read} ABIs
This implements WebAssembly/component-model#524 insofar as it affects validation, componentization, etc. - `future.write` now accepts its payload value as up to 4 flat parameters before spilling to linear memory. - `future.read` takes no payload pointer when it has no payload type - `{stream,future}.close-{readable,writable}` have been renamed to `{stream,future}.drop-{readable,writable}` Signed-off-by: Joel Dice <[email protected]>
