Subject: [PATCH] Fix MIDIMessageEvent.data incorrectly typed as nullable

The Web MIDI API spec defines data as `readonly attribute Uint8Array data`,
which is never null. The `| null` was inadvertently introduced in a DOM
update (#57027). This restores the correct non-nullable type in line with
the spec and MDN documentation.

Fixes #60546
