Automatic update from web-platform-tests Allow JS Self-Profiling in Dedicated Workers Document Policy is now inherited by Dedicated Workers (see https://chromium-review.googlesource.com/c/chromium/src/+/7236250). This change allows the JS Self-Profiling API to be used in workers when Document Policy is enabled and the js-profiling feature is allowed via the Document-Policy: js-profiling response header. This CL also adds WPT tests to verify that Dedicated Workers can use the profiling API when the js-profiling feature is enabled through Document Policy.
