Revert "fix(runtime): Make native modal keyboard interaction consistent with browsers" (#21739)

Reverts denoland/deno#18453

Fixes https://github.com/denoland/deno/issues/21602
https://github.com/denoland/deno/issues/21631
https://github.com/denoland/deno/issues/21641

Reasons for revert:
- alert() and confirm() swallowed ^C with raw mode.
- prompt() did not re-raise the interrupt signal from rustyline. 
- Default 'Y' on confirm() is a bad default and breaking change.
