Remove per-client CORS checks

Those are needed because a request could match with another request made
by a foreign origin, but [1] fixed the issue. This is basically reverting
[2]. Two layout tests are added to detect regressions.

This CL changes the behavior a bit. Without this CL,

 - A response with a proper access-control-allow-origin header for a
   cross-origin request with "no-cors" mode is treated as
   non-opaque, and
 - A response without a proper access-control-allow-origin header for a
   same-origin request with "no-cors" mode redirected from a cross-origin
   resource is treated as opaque

while with this CL,

 - A response with a proper access-control-allow-origin header for a
   cross-origin request with "no-cors" mode is treated as opaque, and
 - A response without a proper access-control-allow-origin header for a
   same-origin request with "no-cors" mode redirected from a cross-origin
   resource is treated as non-opaque.

Also, before this CL, CORSStatus is calculated with an opaque origin for
top-level worklet scripts. This CL changes that: now CORSStatus is
calculated with the origin of the parent context, and so it stops muting
error messages in worklets.
