Forward editing and clipboard events to front components (#22630)

Adds the text-editing events input-heavy front components need:
`beforeinput`, `compositionstart/update/end` and `copy/paste/cut`,
allowed on `input` and `textarea` only.

These events carry payload: `beforeinput` forwards `inputType`/`data`
through a native host listener (React synthesizes `onBeforeInput`
without them), composition events forward `data`, and paste forwards
`clipboardData.getData('text')` capped at 100k chars. Clipboard text is
read only on an explicit paste into the component's own input, never on
copy/cut, and the worker synthesizes a minimal `clipboardData` so
`onPaste` handlers work. `beforeinput` is observe-only: `preventDefault`
cannot cross the async worker boundary.

Allow-listing these events makes the host bind them, so the
`buildHostReactPropsFromRemoteProps` test that pinned them as rejected
now pins events that are still unmapped.
