wasm: set contenteditable on canvas

We don't want to make the top-level screen contenteditable,
since that interferes with accessibility. Instead, make
the canvas contenteditable and install clipboard event
handlers there.

Also move follow-up settings which counters some of the
effects contenteditable (outline: none and inputmode: none),
and move aria-hidden.

Pick-to: 6.5
