chore(website): update the iframe permissions when previewing on web

[byCedric]

Why

Screen wake lock was not enabled. This enables most of the APIs for users to play with in the web preview.

How

• Found the Permission-Policy directives list: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Permissions-Policy#directives
• Added all directives, while disabling a few.
