Expose WebUSB API to worker context

This change updates the WebUSB IDL files to expose the API, minus
requestDevice method, to Dedicated and Shared Workers. The change is
only available via a test runtime enabled flag. The global interface
listing tests are updated to match the newly exposed interface.

The spec for this feature can be found at:

Add WorkerNavigatorUSB supplement

This change adds a WorkerNavigatorUSB supplement for WorkerNavigator.
The WorkerNavigatorUSB interface contains a usb attribute that returns
a USB object. The constructor for this USB object was also changed to
use an ExecutionContext* parameter to allow a worker to properly
initialize the object.

This change also updates the global interface listing tests to reflect
the new attribute that WorkerNavigator contains and adds web platform
tests to check that the WorkerNavigator does indeed have the usb
attribute defined in the supported contexts.

Due to a bug (https://crbug.com/839117) with the WebIDL bindings
generator, the global-interface-listing-service-worker.html test
exposes the usb attribute of WorkerNavigator. Therefore, a check is
performed in WorkerNavigatorUSB to return a null pointer if the
execution context is a ServiceWorkerGlobalScope. Since the intended
behavior for navigator.usb in a service worker is to be undefined, the
web platform test for this checks that condition instead.

Allow WebUSB to work in a Dedicated Worker

This change updates the USB class to allow the exposed APIs to work
correctly in the context of a Dedicated Worker. In order to do this, USB
was reworked to use an ExecutionContext object to check the context and
the FeaturePolicy, rather than the LocalFrame that it was using
previously. The usb layout test for workers was also updated to use the
WebUSB test API to check that getDevices and event listeners work in
Dedicated Workers.

Additionally, the UsbDeviceManager Mojo interface used by WebUSB is
added to the DedicatedWorkerHost BinderRegistry so that the request is
handled correctly.
