Implemented stub ShareService mojo service, for navigator.share.

chrome/browser/BUILD.gn

CL description: it's a bit misleading to say you implemented the service, since
it doesn't actually do anything yet.

Say you implemented a stub service and wired it up to navigator.share.

Also say the platforms are Linux, Chrome OS and Windows only.

Also say that this is only active behind the
--enable-experimental-web-platform-features flag.
