script: initial CookieStore implementation (#37968)

This is a first draft at implementing the required infrastructure for
CookieStore, which requires setting up IPC between script and the
resource thread to allow for async/"in parallel" handling of cookie
changes that have a promise API.

Cookie Store also will need to receive change events when cookies for a
url are changed so the architecture needs to support that.

Expect this PR to be reworked once the architecture becomes more
settled, cookie change events will be implemented in follow up PRs

Testing: WPT tests exist for this API
Part of #37674
