fix: define window.name (denoland#20804)

Closes denoland#20750

This matches what browsers do:
https://developer.mozilla.org/en-US/docs/Web/API/Window/name

In the future we might want to change the behavior to actually update
the process name, but that needs a bit of discussion regarding if
it needs a permission flag (that would make polyfiling `process.title`
setter really easy too).
