Add currentFrame in AudioWorkletGlobalScope This CL adds |currentFrame| property to AudioWorkletGlobalScope according to: https://github.com/WebAudio/web-audio-api/pull/1493. 1. Previously the time stamp (currentTime) was updated when the first worklet processor gets called, and it was inconsistent with how it is updated in the other nodes. Now updating the frame number is streamlined, so the worklet processor also gets the same treatment. 2. In order to streamline this process, WorkerThread reference was added to BaseAudioContext. Due to the GC rule, BaseAudioContext cannot keep a reference of WorkletGlobalScope, so it always derives the global scope from the worker thread.
