<pre>[Streams API] Import the web-platform-tests directly from the spec
https://bugs.webkit.org/show_bug.cgi?id=152051
Reviewed by Youenn Fablet.
LayoutTests/imported/w3c:
These are the web platform tests imported directly (or almost) from the Streams API repository. Tests work out
of the box (all but a small flakiness that we are forcing as failure to not disrupt the execution of the rest of
tests).
To make them work we are importing also the service worker test helpers that is used by the tests.

+ [Streams API] Import the web-platform-tests directly from the spec
+ https://bugs.webkit.org/show_bug.cgi?id=152051
+
+ Reviewed by Youenn Fablet.
+
+ These are the web platform tests imported directly (or almost) from the Streams API repository. Tests work out
+ of the box (all but a small flakiness that we are forcing as failure to not disrupt the execution of the rest of
+ tests).
+
+ To make them work we are importing also the service worker test helpers that is used by the tests.
