CSP: Fix WPT tests for CSP inheritance of dedicated/shared workers

Some Web Platform Test was expecting that dedicated workers served
with Content-Security-Policy: script-src 'none' would block
importScripts and setTimeout because of that CSP. However, according
to the spec, dedicated workers inherit their CSP from the creator
document and disregard the CSPs they are served with.

We rewrite those tests with two different cases. For dedicated
workers, we expect the inherited CSPs to be applied. For shared
workers, we expect the CSP delivered with the worker to be applied.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure .

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
