Power Save Blocker: Eliminate passing ViewAndroid as WeakPtr

As of https://codereview.chromium.org/2103243002/, PowerSaveBlockerAndroid
accesses the ViewAndroid pointer it is passed only at a time when that
ViewAndroid pointer is guaranteed to be valid.  This CL moves
PowerSaveBlockerAndroid away from consuming the ViewAndroid pointer as a
WeakPtr. The concrete motivation is to eliminate WakeLockServiceContext needing
to listen for WebContentsObserver::WebContentsDestroyed() as part of decoupling
the wake lock service from //content.

Decouple WakeLock from direct //content dependencies

As part of the Content Modularization Project, this CL removes direct
knowledge of //content from //content/browser's wake lock service.

The design follows that described here:

https://docs.google.com/document/d/1683obWqUStROtJHgkveAWbnGi-W3P7gMylzYeImEzBU/edit#heading=h.jr0fqceqrud1

Note that this CL does not remove synchronous dependencies of this code
on //content: on Android a callback is passed in in order to obtain
the current NativeView when creating a wake lock. I do not know how to
remove that dependency at this time: WebContent::GetNativeView() can
return different values throughout the lifetime of a WebContents instance,
at least on Android.

Two unittests were removed from wake_lock_service_context.cc as they are not
relevant at the //device level. The functionality of render frame deletion is
still tested via the browsertest.

Content Modularization Project: Move Wake Lock to //device

As part of the Content Modularization Project, this CL moves the
implementation of the wake_lock_service.mojom interface from
//content/browser to //device. It also moves that interface itself
out from Blink to //device.
